: Will 300 dpi (non-vector) result in blurry artwork for screen printing? I created a .psd artwork on a t-shirt that has several "sponsor logos" on it sized at around 1x1inch each. I created

I have been working in screen printing for years doing everything from art prep to screen burning and printing, and as long as its not a cmyk process print with a lot of detail, you don't need vector art. I have had to use images with as low as 72dpi and had no problems. The whole screen burning process helps as a buffer for "bad" artwork, and often can make an image that had to be scaled up 4 or 5 times it's size look much better than the original.

Some common screen mesh counts (dpi) as as follows:

110 - for heavy ink coverage, such as white. To be used for less detail

156 - for moderate coverage

195 - A great all around for coverage and detail (very common, and far less than 300dpi)

305 - Used for high amounts of detail and in CMYK printing. Very restrictive on ink though. This is most likely the highest mesh count that the screen printer will be using, so 305 dpi is pretty darn close to 300 dpi

Also it is important to note that we are working with ink on fabric here. Ink spreads, and it clinging to fibers that are not incredibly precise.

My guess is the person who responded to you is the buffer between the person who preps the artwork. They probably request this because they do not want to hassle with peoples artwork when they send in blurry, tiny images.

300 dpi is a typical print resolution for photographs--not line art. Typically line art would be output at 1200 - 2400 dpi from the RIP software.

Of course, screen printing doesn't have that resolution nor can the substrate (cotton t-shirts) likely handle that fidelity either.

All that said, Alan is correct...listen to your printer.

If she says the result won't look good, it probably won't. In any situation like this, the mantra is "Listen to your printer and follow their instructions." We always talk to the print provider ahead of time, before starting on a layout, if there's anything unusual involved, if it's something we've not tackled before, or even if we're using a print shop we've never worked with. It saves a lot of grief and wasted energy.

Your printer has a strong vested interest in providing the best quality possible, especially on wearable art. If it looks great, people will ask where it was done, and may become customers. If it looks bad, people will also ask where it was done, and won't become customers. You have the same interest, so you'd be wise to follow her lead. She has the experience with her equipment and her production process, has already been through the learning curve on what works and what doesn't. If you've seen samples of her work, and if they were high quality, then definitely assume she's right. (If the quality of her products is not so great, find a different printer, but I'm assuming you chose her because she's professional.)

Printing on cotton fabric is not at all the same as offset printing on paper stock. The substrate is very flexible, so the process isn't nearly as precise.

It's not completely true. But some companies prefer vector for the best image quality. Take the image into illustrator and make it a vector and send it to them.
