<\/a><\/p>\nFor example my logo above\u00a0is vectored and the eye\u00a0below is from the same\u00a0file scaled up to show you that it is still clean.<\/p>\n
RASTER IMAGES : Are a series of\u00a0 dots, called pixels formaing an image.\u00a0 The image is resolution and size dependent and they\u00a0don\u2019t usually scale up or down\u00a0well. The benefit of this type of image is the amount of details and color variations that can be achieved. Most photorealistic images are raster.<\/p>\n The image above is a Photoshop (raster) file.\u00a0\u00a0 It\u2019s also a sample where the image is raster, and the text in the sign\u00a0 could be vector.<\/p>\n This\u00a0 image\u00a0 is a closeup of the face of the center dancer. You can clearly see the pixels, especially between any two different colors. The edges are jagged.\u00a0\u00a0 there is virtually nothing we can do to clean up this design.\u00a0 We cannot “VECTOR” this image to clean it up.\u00a0 All we (or any other artist for that matter) can do\u00a0from a printing standpoint is color separate the design for you.\u00a0 Can anything be done?\u00a0 Yes, of course.\u00a0 However, we cannot add resolution (more dots) to the image.\u00a0 All we can do is apply filters and possibly take some “noise” out of the image.\u00a0<\/p>\n One used to be able to tell what type of image the file was by what program was used and what format it was saved in. Unfortunately, this is no longer the case. Vector programs like Adobe Illustrator (.ai) and CorelDraw (.cdr) can contain raster images within the file. And raster programs like Adobe Photoshop (.psd) and CorelPaint (.cpt)can contain vector elements within the file. Generally it is still true if you have a file created in a vector based program and saved with the file formats; .ai, .cdr, .wmf, .svg and sometimes .pdf and .eps, it is a vector file. And, if you have a file created in a raster based program and saved with the file formats; .psd, .cpt, .tif, .jpeg, .gif, .png and sometimes .pdf, and .eps, it is a raster file. Sometimes the only way to tell what kind of file you have is look at the file zoomed in and see if you see pixels or smooth edges.<\/p>\n For customers who want artwork for screen printing garments. New software programs like Separation Studio, the blend of raster and vector within a file is even more so. Now you can have a Photoshop (raster) file separated and then add type in Illustrator (vector). Both elements will output to the same film as long as the spot color assigned is the same.<\/p>\n If customer provides a raster image (especially photorealistic) that has numerous colors, highlights and shadows, but requests a vector output file. They should be inform that the image may lose details and maybe colors depending on how many colors the printer can handle. However, if separated using a raster separation program, it will have the best chance of looking like the original. Some raster files that have few colors with clean edges can be recreated using a vector base program.<\/p>\n I hope this gives a better understanding of your options.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n
