Hi, i want to change from to dupont artistri to poly power inks, can i just wait for the carts to get empty and top up with the power inks, or do i have to completely flush the whole system and use new carts, has anyone ever mixed these 2 inks and it worked out fine?
thank you

I recommend cleaning the cartridge first. Then put the new ink and do a head cleaning. That should be enough.

Is there any reason why are you changing to Polyprint Power inks? I am also thinking in doing so. After you test the new ink, tell me your opinion.

Good luck.

Hi Caspa, i have heard that the power inks give a more vivid colours on black tees, the dupont i am using now appear to leave a dull finish on black tees, the colours print nice and vivid, but after curing they look dull
hope this helps
thank you for your reply

I know, i have the same problem. That is why i print in 2 passes (at 50% on white t-shirt). The problem with this is the time that it takes to print a shirt. Even using pretreatment the quality is not great. Also the washability is not great. Have you thought on using IA inks (CMYK) the white has to be the one from dupont, the others clog the head.

you print 50% white on black tees?

i have thought of AI but i will lose my warranty on the printer if i change now, they always have us by the balls

The 2x50% is on white t-shirts printing only with (CMYK). This is the only way i got to get good colors.

Maybe with the new RIP it will be possible to do more than 100% of ink.

I use the new rip, but i never use white on a light garment?

I am not using white ink. I print 2 passes on white t-shirts.

Are you using the RIP from CADLink?

Have you tried the polyprint power inks? When you do give your impressions.

No, i was advised by the company that i bought the printer from that it is a tricky job moving from one ink system to to another i was also told that they clog more than dupont, this is probably a marketing ploy because they probably earn more mark ups on dupont inks

They clog more, that's true. Especially black and yellow. Most of my heads died because of yellow then black is the most "popular" to clog.

More pigment and binder, means better print, but more clogs. More maintenance is required...that's all.

The solution:
1. Treat all your inks as white ink and your print-head will last longer.
2. Don't wait for a clog to happen. Set a regular flushing schedule and stick to it.

I used to flush everything every 2 weeks and I was getting clogs. Then I started doing it every week, and no more problems. I minimize the cost by pushing the ink back before I start, and reuse the cleaning solution through a filter.

Hi Bob, thx for the reply, what printer are you using?
Thank you

I have 4 Epson P800 flatbed conversions, and I've built the 3 of them myself
The print-head is not as durable as the one in the Epson F2000, but so far all is good. Each printer has produced around 6,000 shirts so far, with only minor issues.
