Don't know the dimension on a half dvd case. Could it be the same as a CD? 4.5 x 4.5??
I have used matte photo paper and like the results. I found some you can print on both sides, so print something 9"x4.5" and you can fold it in half. With both sides, it's a lot of space to be creative.
My band had our last inserts printed at our campus' student-run printing office. It was .80 USD per page for full-color two sided glossy paper. (We had a 16 page insert, and the CDs still only cost us about $3 each).
The only caveat there is that it was 8.5x11 paper and we had to get it re-printed because the students there screwed it up the first time.
well BenignVanilla, i found the CD Inserts templates from well know online printing services company, they shown many cd inserts templates and i just decided only one which really inspire me so then i order for printed, the size of The trim size of the front part of the insert is 4.75" high x 4.75" wide; the trim size of the tray card is 4.625" x 5.906". it was looks cool when i got the printed files. you can also easily find your solutions via Google search easily. !!!
