I have put an effect on a couple of pictures to decrease the saturation of colours except for the colour black. To apply this effect I used the following set up:
On screen the effect looks perfect, but when I print my document the effect disappears. The original colours of the image are printed.
In my advanced print settings I have already selected normal and high resolution and I have used a preset with a raster/vector balance of 0 (being the opposite of the high resolution setting which is 100). There is no difference visible at all.
If I export the file to PDF, the effect does work, but then another problem appears. When I print directly from InDesign, the colours that are printed match the colours I used in InDesign. When I print the PDF file, the colours are entirely different. For that reason, I want to be able to print directly from InDesign instead of creating a PDF.
Has anyone found a solution to this problem?
Because I will apply the effect to a lot of images. Actually the first layer mentioned above is a placeholder. Together with the black rectangle they form a group. I added it to my CC library. Then I can just drag this group to my document, replace the placeholder with the correct picture and the effect is applied immediately. If there's no solution, I will have to fix all the images (about a hundred) in photoshop...
It sounds like your print driver is not handling the transparency flattening correctly. Try exporting a PDF that handles the flattening and color management on export. Set your Output tab to this where Acrobat 4 forces the flattening and Document RGB including profiles manages the color into a single RGB color space:
I tried this (but for a CMYK document) and it worked perfectly. Thanks!
Also some composite printers color manage vectors differently than rasters. This has come up before and checking Print as Image in Acrobat’s Print>Advanced dialog might help.
Thanks for the help. I'll try this soon and will get back to you.
