This print is perfect man. I hope I can achieve the same thing.

Yeah, this is the same with mine

I have only one strip, maybe same as what you have. Mine emits a very strong light. Actually I jumped into conclusion if the light is really causing the stripes when I tested printing with lights off and lights on and the result is the same as yours. I couldn't blame the ink right now because I have tested 3 different brand of UV inks and stripes are still there. But, I cannot give up on this one, I know there's something I am missing and finding it is my focus right now. I will update this thread once I have the breakthrough what is causing it.

Could be, but changing the lamp that I have right now is a little bit a pain in my wallet 😅. 😔

In my case, although I don't follow the 2cm away from the printed object, I am having the same result, but when I use the rip version 9~ somehow the result got better but still there are very small visible stripes and I have tried 3 different UV ink, 2 different brands of soft uv ink and 1 hard uv ink and the result is the same. My observation is the same with @johnson4 that If I don't turn off the light, the print is perfect but it doesn't cure the ink, and that's the problem. Now what I am doing is I am switching the printhead but before I do that, I am ultrasonic cleaning it first so that the printhead is very clean and free from any clog. I will update you soon once I am done testing.

Ah I see. So, you bought pre-made already? In our case we made our DIY UV from scratch so, the struggle is really hard, specially configuring the C code to match the movement of the encoder wheel to have a perfect outcome. My compution in my code probably is wrong that’s why I am having the stripes. In your case, I think when you bought the flat bed kit, the arduino software is perfect to match all the hardware movement. Good for you man.

By the way, are you using a 30tooth pulley? In my case I am using 20, so probbably that might related to having those stripes? Maybe my computation is wrong? Idk 🫤

That’s a very nice print.

Ok, keep me posted. I hope you achieve the same or much good duality print than what I have. 😀

It has it, use the Partner Rip Version 9.0.3. This is the one that I am using. See my attached files for the sample print. IMG_3722.MOV

Sure, happy printing! 😀

Yes, in my case it was fixed. I was surprised! It's like am printing using a DTF ink. Mee too was using Acro 10.5, I think it was 10.5 not 10.3 as per my previous comment but with version 9, at least in my case it was fixed. I was printing with 1440x790 resolutions for WH and YKCM. Let me know if it works for you, I can attach pictures of my print later because am outside.

Am glad am not the only one experiencing this but I had the work around just last night when I tried to use Acrorip Ver 9~. Since I am using Acrorip DTF Pro 10.3, I've switched to version 9~ and poof! Perfect print without the horizontal lines. I was happy it's not because of the ink, or the type of ink (hard or soft), or even the LED light but it was all related to the RIP software. You must try that if you have a version 9~ RIP and please come back here and let me know what happened in your case?

Do you have a sample print on from your UV printer?

I do cleaning using distilled water only but nothing is wrong with my print head. I also did a very dangerous cleaning like I disassembled the printhead of one of my 1430. So, what I did is I removed the 3 screws that connects the upper and the lower part of the print head. After that, I separated the upper and the lower part and clean the upper part with syringe and distilled water to make sure, the tubes where ink suck from cartridges doesn't clogged with old ink. Then I put everything together, did another flush to make sure there's no clog and tried some print test and, it works very well. Prints are nice like a new print head 😀. My sample print is attached. I don't suggest you to do the same thing because it is risky, but in my case based on my experience, as long as you don't mess with the electronics in the print head, I am fine. P.S. The print head I used here used in different kind of ink, first is pigment ink, then UV ink (hard-type), and lastly DTF ink. The attached picture is a DTF print.

Hello guys, am seeking help on my print. Recently I made a DIY UV printer out from Epson Artisan 1430 and use the same UV light from China and Hard-ink type from China as well. The printer was able to print but if you'll notice the print quality (Ironman helmet), the print layers or horizontal lines are visible. I am using Acrorip 10.5 version to print it. Then I made another DIY UV printer out of Epson 1400 and used a Soft-ink UV curable ink type and the result is the same, the print horizontal lines are visible and there are ink residue on my print. Please refer to the PVC card. I am getting out of reasons why I am getting this kind of print quality? Is the visible horizontal lines are normal? I am not sure also if these things are related to UV light, ink, or the Acrorip software that I am using?
