Cooperation with graphic designers from other similar companies is very important in my job. We send each other a lot of files that we have to edit and then send further. The problem is, each one graphic designer uses different programs. For example, I'm using Adobe package, some other designer using Corel, some other GIMP, and so on.

My company makes plastic parts of shutters. We have many smaller companies inside and designers have full freedom for programs they are using. There is problem with converting each one file because - for example - someone can't read .eps, other one .cdr, etc. So finally we are using converters, which is bad for quality.

The question is: How can I effectively work with other graphic designers?

I thought that maybe we should all find one file extension, but we are all doing works of various kinds - from 3D models, to "beautiful" price lists with a lot of design things, like various backgrounds, feather-opacity headers, tables of contents, we are also doing logotypes, banners... The problem is, that for each kind of work we are also using different versions of programs and we often need to convert these files.
