In photoshop, you can setup your image size by going to Image menu and select canvas size and choose inches and type in your dimensions and the screen will change accordingly to the new size when doing your artwork..
thank you darksider> appreciate the help> i have read that large printing can compromise image quality. was some what familiar with canvas size. just was concerned as far as larger prints and image scaling in relation to fonts and things of that nature

True, this is where you kind of have to use the Resolution formula in regard to what your final size will be, but if it's mainly for Screen printing or heat transfers, i would do full size layouts at 72 dpi should be fine as long you're not scaling small images upward to fit your final size print.. Scaling large images downward to your final size will never cause resolution issue is just the scaling up of small images to fit your final output size that will cause pixelation and loss of sharpness..


Hope that helps, hoepfully I did not confuse you. :)
thank you that was very helpful.i appreciate your assistance. that clarified things even further for me. im mainly doing screen printing. im going to use the 72dpi formula. i havent done any test prints yet but i guess that is really the best method for mastering size and resolution issues.thanks again. im sure glad i joined t-shirt forums
WAIT!!!

72dpi is a HUGE mistake for screen printing or heat transfer. Anything less than 150dpi is horrible. If your computer can handle designing at 300dpi that is best.

If you're working at full size dimension then 72 dpi is fine as long you're not gonna be scaling up the artwork in Photoshop.if you're scaling larger High res images downward, like i said earlier it should be fine.

But you're right you can go higher in the dpi when doing your layouts the more the better,. I mainly keep it at 72 dpi since all my artwork are in high resolution beforehand.
I suggest you print at a minimum of 300 dpi in order to get the best quality of shirts, most places will tell you this before printing, and some might not even do it.
thank you everyone for your advice. that definetly clarified many things for me and gave me a better understanding, i will be posting many questions in the future and im reall happy i joined this forum. much appreciated
Another question for all of you good folk out their in t-shirt forum land? why is it that when i save an image and open the file the image appears to be smaller in my layout? the image size/canvas size option display the size as the same but onscreen it appears smaller?
thank you
Thats zoom factor. use the CTRL and the - + ,or the scroll wheel. This well zoom in and out for ya.

Image Resolution and Canvas resolutions needs to be the same in Photoshop.. Say if your canvas and image were the same size but the canvas was at 300 dpi but your image was 200 dpi when bringing it into the canvas the image will be smaller due to the differences in Resolution.. To remedy this, just match the canvas resolution to that of your images or vice versa..
Be sure to check with your printer as to what size he needs....
tHank you for taking your time out to answer my questions. each bit of information is continually aiding my growth as an artist. much appreciated.
