I bought the system few weeks ago and began to experiment a little bit. I loaded the CD, and found that it doesn't contain much.. I was expecting a whole library of images, but you have to buy those extra from a web site. But since the point is to make your own decals and design them, who cares. You can make a decal from any word file, paint file, image file, photo, etc., so don't worry about the little that's on the CD. When you run the testors software, you get a screen that is essentially the layout of the 5.5 x 8.5 decal sheet itself. While you can create your decal text and images right in this software, I prefer to create the images and text in other programs, then copy and paste into the testors program screen, from where I adjust their final size, then print the decals.
Basically, I found the system to work, but had to try a few things different to get a good quality decal. First, when printing, I found that if I tried to print a heavy black letter or object, the inkjet ink would crack as it dried. I solved this problem by using a very dark gray instead of black. I got a very sharp "almost black" image with no cracking. Next, the fixative. Just spray a few bursts of mist coats until you see its covered. Then let it dry for a few hours. I found my first decals were on the thick side, but that was because I had sprayed too much fixative. I have a Canon S300 inkjet printer, and I made sure that I cleaned the area around the print head, which at first smeared the decal paper. Once I cleaned it with alcohol, that problem was solved. I also used a "fine" or "high" print setting.
There's an instruction sheet in the box, the CD, decal paper (white background and clear), and a small can of fixative. I'm still experimenting and have not tried any small lettering yet, but I will be doing that soon enough. So far, I've done only a 30 pt font and few paint images about 1 in x 2 in.
