This product download contains 25 files. The best marker pens are always the ones that are almost too dry to use. This is a collection of 25 dry marker lines, stripes, checks, zig-zags, and gradients that have a really cool look of transparent overlay where the marker lines overlap. These will add a rough hand-done character to your designs, typography, art, photos, and backgrounds. Excellent for use in posters and flyers! This set includes JPEG and also as a bonus: Bitmap TIFF format files. In Photoshop, Bitmap TIFFs work as normal black and white bitmap images. The trick with bitmap images in Illustrator is that the white area becomes transparent and you can change the black area to any color. This is great for overlaying the marker textures on top of your designs.
