Note: A "spot color" is any premixed color that is outside of the normal CMYK colors. It looks like Scribus actually allows use of spot colors according to this documentation.īasically: set your color swatch up, check the "Is Spot Color" box and then name the color something like "PMS 371" just so the prepress guy has an easier time finding it. The important part is making sure your printer is aware that you are using Black and a "spot color". Pantone colors are premixed using Pantone inks so the CMYK values aren't relevant. To make this simpler, don't even worry about the exact CMYK number that you're seeing there. When you load it into Scribus, it sees the RGB value and then does its own conversion to CMYK, which results in a different CMYK color. What it looks like is happening is that you're typing in a CMYK value in Inkscape and Inkscape doesn't seem to actually support a true CMYK color mode so all it's doing is converting your typed-in CMYK color back into RGB.
RGB > CMYK color conversion isn't an exact science and every program is going to do it's conversion a little differently depending on what color profiles it's using (some use their own, some use your monitor's, some use your printer's). If I should do that, should I pick the closest Pantone to that, and specify it in my guide for any spot printing needs?
Should I use the Scribus suggestions and round up/down to the nearest whole-number values? (I've never seen decimal points in CMYK values, tho' I haven't seen that many style guides really.) If I change the values to the corresponding values given on rgb.to/encycolorpedia (21, 0, 56, 58), it looks a lot further away from the original colour than the Scribus suggestion. When I select and edit the green, the ‘new’ colour Scribus suggests (which looks very close to the original) has CMYK values of 57.25%, 25.88%, 84.71%, 40.39%. Inkscape shows the CMYK value as being 21, 0, 56, 58, which matches what I see on conversion sites like rgb.to and encycolorpedia.īut I’ve read that to create an actual CMYK file to send to the client, I need to import my Inkscape SVG file into Scribus, and edit the colour and export as an editable PDF. I'm using default/flat black and 556b2fff (“dark olive green”). I've got a black and green logo, built in Inkscape. Hi there, I got some great help on a recent thread here and didn't want to keep pestering the last commenter to help with the next step! And maybe the answers to this question can help other beginners like me?
