A view from the other side!
Direct to Gartment will replace screen printing when the marketplace demands that it do so. This process may take 2 years it make take 20 years, but it will happen.
JMHO
I remember when we first started in this industry back in May 1984 (that's 23 years ago) we purchased a single head Melco embroidery machine. The salesman stated, "Yes Sir, embroidery will replace screen printing" and that was the buzz back then. I also remember the same salesman about 5 years later trying to sell us an embossing machine, as the then new replacement for embroidery, and guess where that went. Well, here it is 2008, and screen-printing is alive & well, Thank You Very Much.
Will DTG printers TOTALLY replace screen-printing, I say NO. Will DTG printers be a very good addition to screen-printing, like embroidery is, I say YES!!! It has it's place, and more & more systems will be sold in the future, just like embroidery came of age, so will DTG. However, for what I see as the next several years, when it comes to printing a multi-color design on an auto press that can produce 100-150 shirts per hour, I don't see DTG printers exceeding that volumne & lower cost any time soon. Traditional screen-printing does not require pretreating of shirts, or worring about the now new twist of which mill is making the t/shirt. Only when DTG mfgs. finally figure out a way to print white ink WITHOUT the use of pretreatments, or at least TOTALLY automate the pretreatment process on the same machine (much like the Kornit, but for less than 100K), screen-printing will remain King. Also, the cost of the ink will have to go way down, and the speed of the machines themselves go up, to approach the cost of auto screen-printing. Besides, if you're going to drop 100K for a Kornit system now, one can purchase a very nice new auto screen-print setup for about half of that, and produce a higher volumne at lower cost. Just as a matter of reference, my current contract screen-printer can print a 6 color front & 6 color rear on DARK shirts w/ white base & hilite 144 pcs for $4.05 per shirt, INCLUDING the $15 per screen x 12 screen setup cost. That price drops to only $3.20 per shirt on an exact repeat reorder for 144 pcs. From what I understand about DTG printing, that cost for a dark shirt currently runs about $4.00 PER SIDE. WOW!!!! As I said, DTG has it's place, but not totally replacing screen-printing. Sorry Don!
Just my 2 cents worth of 23 years of pulling a squeege, and standing in front of an embroidery machine. Thanks for reading.
