What kinds of artwork can be used for screenprinting? How do you design a custom piece of artwork? How long does it take to design custom artwork? What do you charge for a custom logo? How should I send you artwork or logos? What file types can I send you? What’s the difference between vector and bitmap files? Do you use Mac or Windows computers? Can you match an exact PMS color? Almost any type of flat artwork ‘can’ be used to create a screen printing design. Some good examples are: drawings, sketches, paintings, photos, digital files, logo slicks, even other t-shirts. Generally, if you can scan the image into the computer or redraw it by hand, we can use it. Having said that, it is very important that you start with a good size and clear piece. For instance, it is impossible to create a 13′ wide design directly from a logo on a business card. The small size does not provide enough information for the computer ( or human artist ) to enlarge the logo to the proper size and still look crisp and clear. Therefore, we would suggest the following guidelines: Generally, the creation of custom designs follow one of two paths depending on whether we are working with spot-color or some form of ‘process’ design. We do not charge for custom artwork that we are going to print on t-shirts or other garments. However, per our polices, we retain all rights to the artwork we produce. If you would like limited reproduction rights ( e.g. for fliers, a web site, entry forms, etc. ) we grant that for free. If you need a custom logo for your business or organization to use with full rights we charge $25-$75 per hour with a minimum of $300. We have the following software and can accept any format that can be opened or imported by these programs: We would prefer Corel .cdr or Illustrator .eps formats for vector files and .psd or .tiff for bitmaps. If you are not using one of the titles above, many other packages can save or export to the encapsulated postscript format (.eps). If your software can only save in a proprietary format we will not be able to open your file. Vector graphics are made up of many individual objects. These objects are defined mathematically as a series of control points joined by lines or curves. Each object is self-contained, with properties such as color, shape, outline, size, and position on the screen. As an example, to draw a red square with a black outline, the software only has to know the position of the 4 corner control points, draw black lines between them, then fill the enclosed space with red. Since each object is self-contained, you can move and change its properties over and over again while maintaining its original clarity and crispness. Vector-based drawings are also resolution independent. This means that they appear at the maximum resolution of the output device, such as your printer or monitor. The image will not loose its proportion or definition when it is scaled up or down. Bitmap, or raster, graphics are actually a ‘pixel map’ that describes how to display an image pixel by pixel on the screen. Bitmaps are very resolution dependent, meaning that if the image is stored at 300 dots per inch (dpi) then every square inch of the picture will have 300 dots or pixels. Each pixel needs color and shading information stored for it. This makes for very large files at high resolutions. Bitmaps also do not scale up very well. If the image starts out being 1’x1′ and 72 dpi (common dpi for web graphics) and you need to enlarge it to 10’x10′ it still only has 72 dots. Now you can see the individual pixels quite clearly and the image looks very jagged. The computer can compensate for this and guess where more dots are needed but the image will be blurry because the ‘guess’ is not perfect. Comparing a vector-based image with a bitmap image. Remember that vector graphics are created as collections of objects and bitmap images are made of individual pixels arranged in patterns. Of the two formats, bitmap images are better for photographs because they tend to offer greater subtleties for shading and texture but require more memory and take longer to print. Vector images are best for drawings that need sharper lines, more detail, and easy modification. Vector images require far less memory and computing resources. Source.
