Try to visit this forum www.t-shirtforums.com. Dami ako natutunan sa site na to. I also learned there na hi-tech na ngayon ang t-shirt printings. All u need are PC, printer, correct ink (pigmented/dye sublimation), correct fabric (cotton / polyester), an iron or heat press and a good design. Yung mga designs mo, pwede mo itago sa PC then print-out na lang kung may o-order. Big advantage against screen printing na your screens will eat roomspace kapag hindi mo kailangan. Just my two cents
yep, you can do this, too. the downside in this kind of printing is, you can not lower your price because the materials are costly, IIRC. the paper that you have to print on using your printer is approximately P30 each, and you can use that only once (i dont know how much that kind of paper cost today). so, if you have to print, for example, 100 tshirts, the paper alone will cost P3000 (assuming that you have to use the whole paper in one tshirt). the advantage with this type of printing, though, is you can print in full color, even photographic images.
while with silkscreen, the overhead cost mainly comes from the set-up, and the set-up is not that costly either. once you have the silkscreen ready, you can print as many as 300 or more tshirts with that silkscreen. the only additional cost that will come out from printing that many tshirt is from the ink that you have to use, which is not that expensive. and, of course, the cost of the tshirt, if you are the one providing it.
