I am a textile screenprinting artist. I use a lot of spot color designs with spot colors. When I need to create a halftone of a color (let's say, "Corel Black", I do a fountain fill and change the tint to a percentage of the color (let's say, 30%). The art is fine while I still have the file open. I can print, and the list of available colors to print as separations will include "Corel Black", with the 30% portion of the design printing as a halftone on the same page with the solid "Corel Black", based on my advanced settings. However, if I save the design, close the file, and reopen it, the object that was "30% Corel Black" is now "100% Corel Black(1)", and is listed as a whole separate color in the print separations list. This happens on all objects with the exception of Text. How do I fix this?? It's extremely annoying when I can't remember the exact percentages I used on the original design, and I have to refill the objects when I open the file later. There has to be an easy solution. This happens with any spot color, not just "Corel Black".
