i have been doing various print material work for some clients for some time. one thing ive noticed quite frequently is in regards to them having issues with the file. sometimes i provide them the file on cd... sometimes through email. when they have trouble with these files its mostly opening them up. i work on a mac and use adobe photoshop cs. i send my files as jpegs. most of my clients use pcs. sometimes they have no issues other times they do. i want to try to minimize this issue as much as possible. is there something about changing the byte order to IBM... would this having anything to do with it? What can i do to prevent this problem? also... recently ive had an issue with a print where the figures face came out messed up... the color was off... the whites were to blown out. i tweaked the color on the computer using photoshop and used a regular monitor and my usual mac laptop monitor ... and the image looked fine on screen. when it was printed it printed messed up. how do you all resolves this issue? what should i calaborate my color preferences in photoshop to? what kind of monitor color settings do you all use? please give me any suggestions. thnx.
