Document Summary
3 ways graphics can be applied to signs. Flat: offset litho, digital press, silkscreen, inkjet, vinyl decals, porcelain enamel, handpainting. Raised: cut solid graphics, fabricated graphics, cast metal, cast plastic, photopolymer, 3d printing. Engraved: sandblasted, acid etched, engraved/router, hand carving. Vector composed of paths (many lines and curves) Sized and scaled without losing resolution or looking pixelated. Typically smaller in full size vs raster. Basically thin lines that are known as paths can manipulate them. Made of pixels (millions of tiny squares) Zoom in: can see square outlines of each pixel. Uses: image on websites, photographs, print (books, magazines, signs) Resolution dependent: loss of quality when scaled. Raster (bitmap) files: composed of pixels and depending on resolution, you"re limited to how big you can make it without pixilation as this. Raster images are usually used for photos and complex illustrations. Vector (line) art: based on mathematics, vector art is completely scalable to any size and never loses resolution.
