Fredrik M Posted June 28, 2019 Posted June 28, 2019 I'm very new to Infinity Publisher, installed it yesterday, but an old fox using first Quark Xpress since 1995 and later on Adobe InDesign. We have developed a way to work with our printing documents where we mix RGB and CMYK colourspaces, everything in color is in RGB, images, vector objects and so on. The only thing in CMYK is black text, and color objects that are supposed to have a certain cmyk value, for example you know that you want 100% Cyan for some reason. Every color object in RGB is then later separated to the requested iso cmyk profile specified by the printers. So i have tried to create a test document using this technique but it does not seem to work, if i change the color mode for one object and select the next on the color mode does not switch in the settings box and therefore i believe that this setting is not selected per object but more for the entire document, am i right here? I have tried to export a PDF file and running it trough our existing workflows and my supposed 100% K text is converted into a cmyk value, this means that the input PDF file had the color setting for this object in RGB rather than cmyk. So is it possible to work with both cmyk and rgb colors in the same document as we have done for many years with InDesign documents. SWB 1 Quote
Staff DWright Posted July 1, 2019 Staff Posted July 1, 2019 How are you adding the RGB objects are they being placed or pasted into the document. Quote

Fixx Posted July 2, 2019 Posted July 2, 2019 What PDF preset / version you have assigned in export? That does make a huge difference. Though while it is normal to let PDF export to do CMYK conversion to pixel images, I do not know if it does anything to vector images (or app native shapes). I always do vectors in CMYK. Quote

I have created my own preset, not sure how this would affect the control panels when in layout though. Quote

If inside AfPublisher, in what panel? Do you mean with "color mode" the color space of an object? Or do you mean the color selector type, like sliders (hsl, rgb, 4c, lab), or wheel or greyscale? Do you mean with "settings box" the Color Panel and its various slider types? If yes, does it switch as expected if you click on the lock icon and then select an object where you expect a different color mode than the momentary sliders show. Or do you mean with "settings box" the pop-up color selector in Swatches Panel to edit a swatch color? If yes, this color selector type appears never to change by itself or automatically, it changes only, if I manually choose a different color selector slider type and remains there regardless of the documents color space. 7 minutes ago, Fredrik M said: I have created my own preset, not sure how this would affect the control panels when in layout though. Did you really notice that an export preset affects the colors during layout? Hopefully it does not, that would be really weird. However, in my experience the most successful way to get K-only objects really reliable as K-only is to export as PDF 1.3 or 1.4. (PDF/X-1 – X-3). That unexpected and unwanted limitation, which is not according to PDF specifications, is, in my opinion, a bug in AfPublisher's color handling. The fact, that in a CMYK .afpub a linked grayscale image with a grayscale profile becomes treated as RGB in AfPublisher by default, though its Resource Manager recognizes the profile correctly, supports my thinking.
