Plastisol Ink Bleeding

Hi guys, I'm a newbie here.

So basically, recently I ordered some plastisol transfers from a screen printer. I had a few different images of roses printed in CMYK.

When I applied them to the shirts I can see there is thin yellow lining appearing on the border of the designs. It makes them look ugly and unprofessional I applied all designs with a home iron. Is this issue due to me pressing them with an iron or due to imperfections in the printing process?

Thanks guys,
Ryan

Looks like a bad print job, honestly. I would not attribute it to your lack of equipment. But look online for a cheap press if you're considering making more of these. Pressure and temperature are important guidelines to follow. It may look great when it ships, but after a few washes, you're going to wish you applied more pressure. :) Cheers!
It's hard to say. This may be a result of the artwork you supplied the printer or could be a result of using an iron. Is it possible the yellow lines you see are shadows in your art?

You can't use an iron to apply plastisol transfers. Like Combat said, you need a heat press.
Thanks for your comments guys. I know I should purchase a heat press to make the whole process nice and easy. But in terms of the designs, no I sent them through to the printer as high res images. There were no shadows of yellow at all.
But even if I were to use a heat press for something like this, would it mean that the yellow lines won't appear? Or what is the benefit of during the press?
that looks like a registration problem in the print. can you take a magnifying loop to the art before transferring it see. maybe through a light table or something?

Look at the word 'Rose'. Unless it's suppose to be two-toned like that, the iron (and your arm pressure) was hot enough to cure some areas but not hot/pressure enough to transfer all. Possible the same with the edges you see.
Yeh I had another screen printer locally say the same thing. Registration issue with printing. What does that mean exactly? Sorry I don't know much about all this as I am not a screen printer but just a regular customer.

So when you create a printed product like a magazine, a newspaper or glossy brochure that has the appearance of photo graph or similar in it, the printing process used 4 colors to create that illusion. The colors are cyan, magenta, yellow and black - that's where the term CMYK comes from. So each color has to be laid down in specific dot patterns and screen angles to form what is called a CMYK Rosette...google CMYK Rosette to see examples. If the screen angle OR the left or right or up and down of any color is off by even a slight margin you'll get that appearance that you are struggling with. I really don't have much experience with clothing work but I have years of graphics and press operation in the paper world and both worlds are very similar. Except ink on paper is easier LOL.....the other thing that can happen is if there is any distortion in the film of any color it can produce similar results. hope that helps a bit
I have dealt with this effect sometimes when working with transfers and I think its a result of the art work and the cutting tool not lining up properly. Basically, the printed art and the cut edge are out of register with each other. As far as I know there is nothing you can do about it once its printed and cut.
Oh okay. Thanks for informing me. Just to clarify, what exactly is the cutting tool? Can you send me a link of what the cutting tool is and what is used for. Thanks a lot

Oh okay that makes sense now. Thank you very much for clarifying.

So in that case I would presume that very few screen printers would perform CMYK screen prints on garments purely because it's very difficult to achieve perfection. Correct?

I've seen really nice 4 color and 6 color work from screen printers. the only thing I've noticed it's usually significantly fewer dots per inch than paper world to create their work. Which makes sense since it's getting put on woven threads instead of glossy paper. I don't really know how they pull it off for sure but can only imagine it takes great skill and good film work before printing. I do know however most screen shops I've bought from prefer spot color work with "loose" registration just to avoid the hassles
