I design wraps for race cars and have my buddy print them for me, then I install them. I make my file using SAI's Lxi Master Plus V11 and export to .pdf normally. I have had an ongoing issue of exporting. I can try .pdf, .ai, .eps, and EVEN .jpeg(for proofing) and it will cause certain colors, gradients, or fills to go "missing"(appear silver-ish)..... I use my HP laptop with Adobe CS4 to open the files as does my buddy. If I open the program, open the file, and export, 85% of the time it will export "OK", but if I keep the program open and do another file it will do the same thing. I'd have to close out and re-open the file to export every single time which is time-consuming and frustrating. Is there anything I should look for or has anyone had this issue??? Any tips or tricks would be appreciated!!!
