Filling CMYK image with colour


Recommended Posts

Bug or just an idiotic experiment which never happens in "real life"?

My setup: Placed CMYK image; colours = C0M100Y100K0, C0M0Y0K80, one spot colour

Step 1: Fill image with pre-defined 100% K from swatch. Colour of image changes to whatever Publisher calculates. Revert the action.

Step 2: Fill image with 80% K. Colour is completely different from the result of 100% K. Revert the action.

Step 3: Fill image right after another with the red, the spot colour and 80% K. Colour is different from step 2. What is Publisher doing here? Adding colours? I would expect, that once you change the fill, it is like setting the fill to None and then applying the other colour.

Sorry, I was unclear. I didn't mean the source of the colors.

I meant: Exactly what steps are you taking when you say that you "fill the image". I can think of several ways of filling an image, and some of them would perhaps have the effect you have described.

Having a sample file with your image and swatches would also help.

Will do so, but due to the pending Brexit a download of British software takes more than a hour, but probably I am just sitting only on a slow connection. :(

It's very slow here, too.

Still the same. But I can get it even more complicated. To eliminate error sources I added C0M0Y0K100 and C0M0Y0K0 to my palette.

Try 1: Filling the image from palette with 100% K or 80% K or White does seem to fit.

Try 2: Filling the image from palette with Red, HKS 7 and 80% K seems to add? / multiply? colours.

Try 3: What the fourletterword are the colours right to the palette dropdown in Swatches panel are meant for? The rectangle with the red line means "No colour", so far so obvious. The next three ones I strongly believed, that they represent 100% K, 50% K and White are ... what?

Thanks, I will test this. If it is so like you said, then in IMHO handling images in Publisher went the wrong way. I don't see the benefit (yet) handling / placing / manipulating images in two different ways.

We believe this has been addressed in the latest (#371) beta build. Please retest this behaviour.
