Screen printers have specific needs because, inevitably, they get smaller orders than they would like. They also have the problem of huge set up costs and processes before they can make their first print. There is a whole category of high color prints in small quantities that are much better suited for a D2 printer, or white toner printer, or HTV (heat transfer vinyl).
Not only that, but the very worst nightmare a screen printer has is producing a job that took them six hours to set up, only to find out that the school, church, or business wants to order three more shirts. It’s tough to go back to your customer and tell them you want another $300 to cover the costs for their six-color print. So, at some level, all screen printers have to have the means to handle these orders out of necessity.
The key is to get good with Photoshop filters which can simulate the half-tone look of your screen printing. Screen printers will also want to find equipment that is easy to use and can produce quick prints. Most D2 machines will easily print whatever you can load up, but only certain brands have built-in filters to make the prints simulate a screen print.
They will want to develop a set process and procedures that allow them to use the same artwork for both their screen print machines and their D2 or WT (white toner) printer.
