Placing data with effects into
InDesign
If you export data created in Illustrator or Photoshop with special effects such as outer glow as
native data or PDF exported from an application, place it in InDesign, and then export it as PDF/
X-4, there are times when the output from Trueflow Advanced PDF is not correct.
This problem cannot be confirmed in Acrobat and occurs in output from Trueflow.

Versioning workflow
A versioning workflow uses layers rendered using PDF and is a method for output of multiple
versions of the same document, which enables both a workflow with layered output function
and support for multiple languages. This workflow can also be used with PDF/X-4 data.
This workflow is supported by InDesign CS2 - CS5 and Illustrator CS2 - CS5.
Follow the steps below to create the data.
1. Create the data for the application layers (see the manuals for the individual applications).
2. See "Creating PDF/X Files in InDesign CS2 - CS5" (P50) or "Creating PDF/X Files in
Illustrator CS2 - CS5" (P55) select "Trueflow RGBwf 1.3J.joboptions" in "PDF Export
Presets", and create PDF data containing PDF1.6 format layers.
3. See "Verification and confirmation of PDF" (P67), and convert the PDF1.6 to PDF/X-4 in
the PDF fixup settings in Acrobat 8 to create the PDF/X-4 data with layers.
Font preflight problems
If you input PDF that uses functions from PDF1.4 and higher or separated PDF, the font results in
Preflight may be NG if one of the following conditions is present. Corrupted characters do not
occur in the actual output.
• Embedded Type 3 fonts
• Fonts that are not actually used in an illustration but for which there is information in the PDF
With following versions of Trueflow, this
problem has been fixed.
•Ver5.01 TF175
•Ver6.01 TF135
•Ver7.10 TF110
•Ver7.20 or later
A versioning workflow that uses these PDF
layers is supported by a workflow that uses
Adobe PDF Print Engine for Trueflow SE
Version 6.00 and later. See the Versioning
Operation Manual that is included with
Trueflow SE for more information.
You cannot create PDF with layers even
if you use the "Trueflow PDFX4 1.3J.
joboptions" PDF preset file for creating
PDF/X-4 that is provided in Adobe CS3 -
CS5. If you use a versioning workflow, use
"Trueflow RGBwf 1.3J.joboptions" even
for Adobe CS3 - CS5.

PDF with transparency effects
outputs completely blank
If you input PDF that includes transparency effects and the following conditions are present,
illustrations may shift position on the page or the output may be completely blank.
• When the "Prepress Margins" setting in the "Other" tab is Off
• When a negative value is set for the MediaBox or other origin coordinates in a PDF file
As described in "Bleed" (P37) this problem can be avoided by accurately designing bleeds and
creating data with an awareness of the page origin.

Text missing on vertical text
with transparency effects
In InDesign CS2 - CS4 and Illustrator CS2 - CS4, if you apply transparency and overprints to
vertical text and output it in PDF/X-1 format, a problem causing text to appear to be missing
when displayed in Acrobat 9 may occur. This problem does not occur in Acrobat 8.
This problem does not occur in Trueflow, but it is necessary to be careful because if you place
that data in InDesign CS4 or Illustrator CS4, the data ends up with unavoidable bugs.
Acrobat Distiller 6 font
embedding
We have discovered that there are serious bugs when embedding Japanese fonts in Acrobat
Distiller 6.
As of now, we have confirmed that the bug occurs under the following rare
conditions.
• When an Illustrator native file or PDF is imported into InDesign
• When the PostScript output from that document is converted to PDF using Distiller 6.
If these conditions exist, on rare occasions, font embedding is not performed correctly, and when
the data is opened in Acrobat 6, the following error message is displayed. When you check the
font area of the Document Properties dialog box, Embedded Subset may not be displayed for the
font, or no error message appears and some characters are missing.
As a result, characters are either corrupted or missing in the output.
This bug has been fixed in InDesign CS5
and Illustrator CS5
This bug has been fixed in Acrobat 7.

We have confirmed that this problem can be avoided using any of the following methods.
• If you are importing an Illustrator document, import it in EPS format.
• Directly output PDF/X-1a format from InDesign CS.
In addition, the PDF/X-1a data may pass Preflight in Acrobat 6 with No problems found even if
this type of bug occurs, so if you cannot create data that meets the conditions above, if you are
concerned about a complex document, it is necessary to check it very carefully by eye.
With PS created in InDesign
2.0.2
When PS created in InDesign 2.0.2 is converted to PDF/X-1a data using Acrobat Distiller 7,
the data may not pass the check in Acrobat Distiller 7 due to an "Invalid BleedBox Offset". This
occurs because information is encoded in PS created in InDesign 2.0.2 so that MediaBox is
slightly smaller than BleedBox (MediaBox is included in BleedBox). Although Acrobat Distiller 6
accepted such data, it seems that Acrobat Distiller 7 does not accept it.
When you create a PDF/X-1a from a document created in InDesign 2.0.2, enlarge the page size
(MediaBox), for example, by adding register marks and then create a PS or convert the data into
a InDesign CS/CS2 document and then output it as a PDF/X-1a directly.
InDesign CS - CS5
Multiscreening
There is a problem where by PostScript data output from InDesign does not include halftone
screening information that is included in imported PhotoshopEPS. Therefore, multiscreening
cannot be used on InDesign. Even in this case, it is possible to specify multiscreening using
TrapEditor MS after inputting data into Trueflow.
Application of Transfer
Function
In order to apply the Transfer Function specified in Photoshop on InDesign CS or later, the
"Override Printer's Default Functions" checkbox must be checked in the Transfer Functions setup
window of Photoshop.
At the same time, the "Include Transfer Function" checkbox in "EPS Options" must be checked
when saving as an EPS. (In InDesign 2.0.2 or earlier, there was a bug whereby the Transfer
Function was not applied properly.)

Operation using DCS format
EPS images
When DCS format images were used in previous versions of InDesign, it was necessary to
perform the OPI processing in Trueflow. In InDesign CS, however, DCS images can be converted
to composite and embedded in PostScript data, so the OPI processing in Trueflow is not required.
Since this function is designed for images created in Photoshop, the OPI processing must be
performed for DCS format images created in other applications as before.
Perform OPI processing in accordance with the description, "[ Omit For OPI ] :" (P73)
Illustrator EPS data containing
spot colors
If data from Illustrator 10 or earlier contains EPS data that includes spot colors and that EPS data
is imported into InDesign and output as PostScript, PostScript with coding inconsistencies is
generated and an error occurs.
If you use EPS data that includes spot colors, use Illustrator CS or later.
Specifying an RGB color of
"0, 0, 0"
If an RGB "0, 0, 0" color is specified for objects such as text, keylines and fills in InDesign, the K
separation does not become 100% during output, and the data is converted into the four CMYK
process colors. (InDesign specification)
Do not specify colors as RGB colors in InDesign, and specify them as CMYK colors instead.
(* It is not applicable for the RGB workflow.)
Transparency and blurring
effects
When processing grayscale images with transparency and blurring effects applied in InDesign,
unwanted lines may appear on the images depending on the resolution.
OPI settings for GrayTIFF data
If you process PS with values other than 100% specified for the shading (density) on GrayTIFFs
colorized in InDesign, turn on the following OPI options in the Trueflow import job ticket.
• ALD
• EPS
• GrayTiff

InDesign CS - CS5

If you set up OPI processing such as the above for data that includes GrayTIFFs colorized with
spot colors in InDesign and the high res images are not present, the colors in the low res image
areas are output lighter. (This problem does not occur if you colorize with process colors).
Layered output function
When using the function to output the image with other data overlapped in part in Trueflow
(layered output function), if PostScript is output from InDesign using the color of "In-RIP
Separations", the image that positioned underneath will be hidden by the overlapped data. This
occurs because a white object that is the same size as the image will be output. When using the
layered output function for the data created in InDesign, output the data in a PDF/X-1A format.
Positioning of PDFs in
InDesign
With all versions of InDesign, when a PDF is positioned as an object in a document, it has been
confirmed that problems such as the omission of images occur.
*1)
Due to this, positioning of PDFs
in InDesign documents should not be attempted. However, this problem does not occur when,
for PDF/X-4 applications, an IllustratorCS2 native file (structurally PDF format) is positioned in an
InDesignCS2 document or, similarly, when a transfer is made from IllustratorCS3 - CS5 to
InDesignCS3 - CS5.
For further information, refer to "Illustrator CS2 - CS5 native workflows" (P6) .
"Effects" in InDesign CS3 - CS5
If you use the following from "Effects", which are supported in InDesign CS3 and later, output
problems may occur if the target objects are rotated. This also occurs in InDesign CS4 and CS5.
• Bevel and Emboss
• Inner Shadow
• Inner Glow
• Satin
To avoid these problems, you can create the same design in Illustrator and place it in InDesign
for output or output PDF/X-1a from that InDesign document to convert the effects to images for
output.
*1)
This occurs with high frequency when
PDFs output directly from QuarkXPress
6.x, which is not supported by Trueflow,
are positioned in InDesign.
With following versions of Trueflow, this
problem has been fixed.
•Ver4.01 TF185
•Ver5.01 TF175
•Ver6.01 TF135
•Ver7.10 TF110
•Ver7.20 or later

Problem with composite fonts
in InDesign CS2 - CS4
If you directly output PDF/X-1a from an InDesign CS2 - CS4 document that uses composite fonts
and display it in Acrobat 7 or Acrobat 9 (or Acrobat 8), there are times when differences appear
in the display.
There are times when the same problem occurs in conventional Trueflow RIP'ing.
When you look at the problem, it appears as if it was corrected in Acrobat 8 and later, but the
actual cause of this problem is in the encoding of the PDF output from InDesign. We know that
Acrobat 7 and Trueflow output results conform to the PDF standard (differ from the display in
InDesign). For printing, if you cannot achieve the results you see in Acrobat 9, which is to say
InDesign, problems will occur.
Illustrator CS - CS5
"Replace vignettes" in Trueflow
If you process data that includes gradients using the import processing with the "Convert
Gradients to Smooth Shades" option set to OFF, there are times when the gradients are left out or
the quality is lowered. Normally, set the "Convert Gradients to Smooth Shades" option to ON in
the import processing.
However, as an exception, if you process data that contains objects with special effects over
vignettes, density differences may occur in the vignettes around the objects. If this happens, you
can turn the "Convert Gradients to Smooth Shades" option off in Input processing and avoid this
problem by not replacing the vignettes.
This InDesign bug has been fixed with
InDesign CS4 6.0.4 or later.
With following versions of Trueflow, this
problem has been fixed.
•Ver4.01 TF180
•Ver5.01 TF168
•Ver6.01 TF125
•Ver7.00 TF017
•Ver7.10 or later

Objects converted to images
If data contains Illustrator effects such as transparency, blurring or drop shadows, the target
objects are converted to images and saved. As a result, there are times when the output results
from the areas that were converted to images are blurred or have banding.
Conversion to proxy colors
from spot colors
When spot colors with the same name but different proxy color values are used and
impositioned on an identical page / signature, even if these spot colors are imported with the
"Load spot colors" option set to ON in the import processing template, all the spot colors with
the same name will have an identical proxy color value.
If you want to register them as temporary spot colors for data creation and then later convert
them to separation process colors for output, set OFF for the "Load spot colors" option in
the import processing template to convert spot colors to process colors. If you want to use
QuarkXPress Versions 4.1 and 5.0, it is possible to convert spot colors to process colors from the
proxy color values set for each object by using the TP-X spot color adjustment function.
PDF
• PDF1.4 format data directly output from Illustrator CS2 cannot be output properly. Use data
saved as PDF/X-1a or EPS, not the PDF 1.4 format data that is output directly from Illustrator
CS2.
• If both transparency effects and the gradient mesh function are used when creating PDFs in
Illustrator, the gradient mesh objects may be left out.
• When outputting PDF from Illustrator CS / CS2, embed the images rather than linking them. If
images are linked, unwanted lines may appear on the images.
This problem was fixed in Illustrator CS3.
OutlinePS / EPS in Trueflow
There are some points to note when creating OutlinePSs and EPSs in Trueflow from jobs that
include Illustrator data.
Refer to "Notes on Using Trueflow" for more information.
Transparency gradation in the
IllustratorCS4 or later
Adobe Creative Suite 2 and Acrobat 7 or before are not functional for transparency
gradation data which is newly supported in the IllustratorCS4. To output the data in the
InDesign, use the InDesignCS4. (see "Illustrator CS2 - CS5 native workflows" (P6))

Text and transparent gradients
If you use Illustrator CS4 and later, use transparent gradients on text and export the data in PDF/
X-4 format, it is not displayed correctly in Acrobat 8 and earlier.
If you convert to PDF1.3 in Trueflow, the same problem occurs.
Photoshop CS - CS5
When DCS is created in
Photoshop
As above reason we recommend Photoshop CS or later for DCS image.
If a file is saved in DCS or later format with "No Composite" in Photoshop 7 or Photoshop CS or
later , the OPI processing is not performed correctly in Trueflow. This bug has been fixed so that
saving the file with "Color Composite" ensures correct processing.
In addition, if a DCS image is created with JPEG encoding in Photoshop 7, the data will be
invalid and an error will occur in Trueflow. This will not occur in Photoshop CS or later.
With a DCS2 image created using Photoshop 6 or earlier, lack of any CMYK separations will
cause an invalid data error.
History Log
When an EPS file with a history log embedded is saved using the History Log function of
Photoshop CS, if the history log becomes large by many editing operations, the log exceeding
the size limit of PostScript text will be recorded in EPS, which causes an error. Do not use this
function.
QuarkXPress 6.5 - 8
Upgrade recommendation
QuarkXPress 6.5 has been released with many bugs fixed and it now supports the dynamic
download of the OpenType fonts. If you have any problem with QuarkXPress 6.1, we

About direct exported PDF
Direct exported PDF by QuarkXPress 6.5 is not supported. And PS file which is created by
"Create PostScript File for Later Distilling" option (in "Preferences" - "PDF") is not supported.
QuarkXPress7
*1)
and later support PDF/X-1a direct export.
Separation PS
With using Trueflow, it is not recommended to use Separation PS.
SeparationPS with QuarkXPress 6.5 / 7.0 / 8.0 is not supported.
QuarkXPress 6 gradients
The gradients set in QuarkXPress 5 or an earlier version were replaced in Trueflow and output as
smooth gradients. However, as the gradient encoding pattern has been changed in QuarkXPress
6, the QuarkXPress 6 gradients are not replaced in Trueflow and output as they were coded in
PostScript.
Therefore, the quality of the QuarkXPress 6 gradients may be degraded when compared to the
output of gradients that were created in the earlier versions.
With QuarkXPress 7 and later, the software has been modified so that gradients are encoded as
smooth shading for both PDF and PostScript output. There is no need for encoding replacement
in Trueflow in order to achieve smooth gradient output.
Length limit for spot color
name
When a spot color name has 32 or more characters and "DeviceN" is selected for the print color,
an error may occur in Trueflow. Use 31 or less characters for a spot color name.
Spot color for the box frame
With QuarkXPress 6, even if spot colors are set for the frames of boxes, they cannot always be
output correctly.
Table creation function
With the QuarkXPress 6 table creation function, the on-screen image is different from the output
result depending on the conditions. Before the table function is used, confirm that the output
result is appropriate.
Page information text
With QuarkXPress 6 , Document name, Date, Page text, which appears beside the register marks
outside the finished page area, is output as bitmap. With QuarkXPress 7 and above, there are no
recognized problems.

QuarkXPress 7 has been released in
Europe and the USA.

Support of DCS2
When you output documents in a DCS (or DCS2) file that is intended for color separation
process, copy the image to Trueflow and perform the OPI processing in Trueflow. This enables
you to output the documents correctly even in composite printing.
When a document containing DCS (or DCS2) images is output in a DeviceN form using
QuarkXPress 6, the message "You are about to print pages that contain DCS graphics which may
produce unpredictable behavior when using DeviceN. Do you want to continue?appears. If,
however, the OPI processing in Trueflow is effective for all the DCS images in the document, the
output can be done with no noticeable problem.With QuarkXPress 7 and above, OPI processing
is not supported for DCS files in Trueflow.
Print Style files
From QuarkXPress 6.5, it is possible to set the bleed value in the printing format file.Note,
however, that "Trueflow Style ver2.1" does not include the bleed value. Therefore,before
outputting PS, set the bleed value to the same as the offset value in the Layaut tabas instructed
in the PS creation procedure or create a new printing format file that includes the same bleed
value.With QuarkXPress 7 and above, the output style also includes the bleed values.
Blank plate auto detection
function restrictions
If images with CMYK components are included in the import data, all of the process colors are
output regardless of the pixel count of the image data.
When the image data that include gradations are processed, unnecessary plates may be output
due to improper color detection.
(Example: rectangular blend and diamond blend generated in QuarkXPress)
Transparency effects
If you use transparency effects in QuarkXPress 7 or 8, objects may shift slightly or streaks may
become apparent in the places that were flattened during output.
Importing native Illustrator files
If you import native Illustrator files into QuarkXPress 8, data on which the opacity mask function
was used may not be output properly.There is no problem if you import the data in EPS format.
