I have a regular job doing a magazine cover. My workflow is to edit the image, then flatten it and convert to CMYK TIF for the client with the profile they supplied, then send it to them with Yousend it. Although the pixel dimensions don't vary, the file size does, but is usually a reasonable if large file - around 30MB tops.
Today, my flattened file is 342MB, way larger than my usual file size and obviously rather problematic to send.
Anyone got any ideas how this happened and what I can do to get it saved at a smaller size?
16 bit w/ extra alpha channels? Inadvertent uprez or resize? That's a big jump in file size, probably more than can be accounted for even if you did both of those things.
I was going to suggest the metric dimension but it's already there. The other big variable is compression. I alway zip compress my yousendit files, as it often dramatically decreases the file sizes and shortens the upload and download times, but for me, 30 mb would be tiny. I'm often slinging files between one and two gigs, and any size reduction there makes a difference.
