Two quick questions:
1) I ordered a yellow enclosure with only black text and graphics on the COLOR layer, but I didn't do a white layer underneath, should that still be OK?
2) I just noticed in the Tayda instructions about the strokeless, colourless box in the COLOR layer - what is that for? I left that out, is that a biggie?
2. I left that out too, I think that's just part of their sample file. I don't think that matters at all...
1. Black should print fine over yellow. You'll only run into a problem when printing lighter colors on darker enclosures...
3. I may have figured out the white spot color issue, and with the help of a friend who works with illustrator everyday I was able to test it out... It turns out that creating a spot color in affinity is necessary (and way more cumbersome than I would have thought), even if the Roland color palette is used.
Here's the way I did it:
Import the Roland palette,
create a new global color,
use the same color value as the Roland swatch,
set it as a spot color,
name it RDG_WHITE2,
Apply it to the items in your white layer,
Delete the original white swatch,
Rename the new spot color RDG_WHITE,
Pour beer,
Repeat for RDG_GLOSS,
After all the spot color nonsense is over (And I think jcrhee is right, you'll have to do the above for each document) export as PDF/X 4...
I'll confirm that this worked
for real after Hugo gets back to me.
