Convert to Multichannel Bitmap is not available in coreldraw 2020.I had created a multi channel bitmap in illustrator.. by grouping vector pantone gradation, cmyk bitmaps and vector. The same AI file when imported in Coreldraw .. the bitmap showed as Multichannel Bitmap in the bottom status bar.
My question is why can't we do this in coreldraw. Convert a set of grouped objects, (Vector, CMYK, Pantone etc)in to a Multichannel Bitmap. I don't want the pantone shades to be converted to CMYK.
from what I understand your file when imported from illustrator to corel presents problems, is that it? If this is the problem, the solution is to save in illustrator, do not activate the option (use compression)
some problems are solved like that, bad about color differences I don't know if it solves for sure
