I need some help understanding these things as I have no educational background or training in digital media. I just like to draw and I want to be sure I have it right. :) "Acceptable file types include: CMYK Photoshop TIFF or Photoshop EPS- minimum of 300 pixels/inch resolution; Illustrator (10 or 11.0) or Illustrator EPS files." Does this mean in Photoshop when I chose file NEW and fill in my width/height, I chose CMYK Color for the mode and should make resolution 300 pixels/inch ? or is there some other way to do this? When saving my document as a TFF I get option of Byte Order of IBM PC or Macintosh. I chose IBM PC ...but should I check off LZW Compression ? I'm not sure what is for. Printable color I assume is taken care of by setting it to CMYK, please correct me if I am wrong. What is a 'professional file construction' considered to be? I usually save my drawings as jpgs and psd file to preserve all layers if I want to go back and change something. I noticed when I saved as TIFF it flattened all my layers. Maybe I did something wrong? Thank you in advance to anyone who could shed some light on these for me. I greatly appreciate it. Mari
