Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
Although initially mandated by my inexplicable loss of higher halftone functions in my Corel 12, In the interest of giving custy's the most accurate proofs possible. I tend to place separate tiff files into my documents for haltones...If you have photoshop, (for a simple deal like this) it only takes a minute...Create a Grayscale doc in p-shop the same physical size as your corel doc at 300 lpi. select entire area (ctrlA) and fill with either a gradient to your liking, or in this case, using the "fill" tool, a percentage of Black. ( I would go about 40%) convert to TIFF, set halftones angle/dpi to your liking...save it where you can find it, and import into corel. Whew! Still with me? Almost there! with tiff selected, set your fill to nothing, & your OUTLINE to whatever named pantone color you want...using power clipping, paste the tiff into the outline of your bkgd mascot shape, et, Voila! You will have an exact depiction of how it will print on a shirt (Less possible dot gain, but average custy will never notice...Edit: Sorry, forgot...the coolest by-product of doing it this way (at least with muliti-color jobs) is that your dots will "nestle" in perfect "butt" registration with a second color...An end result (AFAIK) that is impossible using standard higher halftone output options through Corel...dots won't nestle, they stack...2nd edit: Sorry, one last thing...resulting field of dots will look "grainy" & rough, fear not, this is merely Corel's preview of a tiff, dots will print out nice & crisp on seps!
Send me the file via pm, I will take care of it for you, no biggie! ;o) But for doing it in house, just do away with the lens effect, & substitute a simple 35% (or whatever % you feel is appropriate) of your solid blue, & output a sep using your desired HT settings in the print menu!
