Pros : Easy to use & transfers colors & design to glass surface faithfully. The Color Slide provides for different levels of transparency depending on the colors in the graphics. You can enhance those colors with your choice of glass color. The creative possibilities are endless & this is a great way to add art & color to your glass creations. I originally bought the Color Slide to permanently transfer graphic designs to clear glass cutting boards. I reverse printed the designs on plain white, copy paper & used a local printing outlet's color copier to transfer the images to the Color Slide sheets. The images printed to the Color Slide sheets beautifully (with one exception, as noted in cons). I was very pleased with how the images then transferred to the glass during the baking process. I attached stained glass to the back of the cutting board,over the graphic, providing a colorful background for the Color Slide image. Now the finished project is both art for the wall & a unique cutting boar
Cons : During the copying process the Color Slide sheets were getting jammed in the copier because the heat generated by the copier melted the Color Slide film. I wasted a few sheets at first. I decided the leading edge of the Color Slide sheet, to be copied to, needed to be connected more firmly to the backing it comes on so it wouldn't get jammed in the copier. I used scotch tape, which worked perfectly. Just make sure you leave enough space between the leading edge of the Color Slide sheet & your design so that when you crop the graphic you have the recommended boarder width left of about a 1/4 inch.
Other Thoughts : It would be nice if the Color Slides were offered for sale in various sheet amounts so that there would a discount for larger sheet count purchases and I think the directions for use that come with the packaging is vague. There should be some text about why you have to use a laser printer or a color copier.
