Why does this matter?


Well since your asking, if you are going to be investing serious money into getting some high quality screenprinting done,  you would want the best print  possible you? We know we would, and we sure want you to have it too.

In order for us to give you the best possible print we need the best artwork you can give us.  Make the image that actual size you want it at 300DPI

If you give us a postage stamp size jpg image we can't blow that up to A3 size on a tshirt without it looking terrible.
Were good at what we do, but not that good. If we ask for better artwork it's because after years of doing this we know what's goning to work or not.

So if we ask you for a better image this is why, if you don't have the skills to do this yourself
(or know a friend who can help you out!)

for a fee we can book one of our talented graphic artists to help out.
They practically bleed pixels, so they know what they are doing.

We accept the following file formats:



If you are using vector art, please outline your fonts before uploading. If you do not have a vectorized version of your art, use the largest size and highest resolution image that you have available (150 dpi or greater is recommended for best printing results).

If you can not get your logo to display correctly in the Design Studio, you may email it to us at info@opmdesign.com.au and we will convert it to a format that is compatible with the design studio.



JPG (or JPEG) is a raster image that is often used for photographs on the web. JPGs can be optimized, when saving them out of photoshop, to find the perfect balance of small file size and high quality. On the web, you want your images files to be as small as they can be so your site loads quickly, but large enough to still appear crisp and not pixilated. A JPG can’t have a transparent background so they are always in the shape of a rectangle or square with a solid background.


PNG is another raster image type. For the general marketer, the main difference to understand between a PNG and JPG is that a PNG can have a transparent background and is generally larger and higher quality. Therefore a PNG is ideal for saving logo files for websites because they can be placed over a colored background.


A GIF is another raster image type. A GIF is formed from up to 256 colors from the RBG colorspace. The fewer colors and shades contained in an image, the smaller the file size. Therefore a GIF is ideal for images that use just a few solid colors and don’t have gradients or natural shades. You wouldn’t want to use a GIF for a photograph.


A TIF (or TIFF) is a large raster file. It has no loss in quality and therefore is primarily used for images used in printing. On the web, because of load time, you generally want to use smaller images such as JPG or PNG.


An EPS file is a vector file of a graphic, text or illustration. Because it is vector it can easily be resized to any size it needs to be. An EPS file can be reopened and edited.


An AI file is a proprietary, vector file type created by Adobe that can only be created or edited with Adobe Illustrator. It is most commonly used for creating logos, illustrations and print layouts.


First the basics

*A PDF is generally a vector file. However, depending how a PDF is originally created, it can be either a vector or a raster file.  Whether you opt to flatten the layers of your file or choose to retain each one will determine the image type.


Raster images use many colored pixels or individual building blocks to form a complete image. JPEGs, GIFs and PNGs are common raster image types. Almost all of the photos found on the web and in print catalogs are raster images.

Because raster images are constructed using a fixed number of colored pixels, they can’t be dramatically resized without compromising their resolution. When stretched to fit a space they weren’t designed to fill, their pixels become visibly grainy and the image distorts. This is why altered photos may appear pixilated or low resolution. Therefore, it is important that you save raster files at precisely the dimensions needed to eliminate possible complications.


Vector images, alternatively, allow for more flexibility. Constructed using mathematical formulas rather than individual colored blocks, vector file types such as EPS, AI and PDF* are excellent for creating graphics that frequently require resizing. Your logo and brand graphics should be created as a vector and saved as a master file so you can use it with smaller items such as your business card and letterhead, but also on larger surfaces, such as your corporate jet. When necessary, always create a JPG or PNG for use on the web from this master vector file. Just be sure to save the new raster file in the exact dimensions needed.


The web, historically, displays 72dpi (72 dots or pixels per inch) – a relatively low pixel density however most modern displays are now much higher. That said many images on the web are still in that 72-100 dpi range. While monitors can display higher resolution the web also needs to optimized for speed so images around 100 dpi hit the sweet spot for looking great on a screen but also loading quickly. Raster images with a low DPI in the 72-100 look nice and crisp on the web. But this same low DPI image will probably not be suitable for printing on a garment.

To correctly print an image, it should be at least 300dpi, a much higher pixel density than the web displays. Resizing a low DPI image pulled from the web to fit the dimensions of your print project won’t work because the same finite number of pixels only get bigger and begin to distort. For example, let’s say you want to print your logo at 60mm x 60mm on a tee. If have a 72dpi jpg of your logo and it’s 60mm by 60mm, it will need to be “stretched” to more than 3 times the size to get it up to 300dpi. That 72dpi logo may look great on your computer monitor, but when it prints at 300dpi it will look pixilated. Instead you should use a vector version of your logo (.EPS or .AI) or create a raster (JPG) with the exact dimensions desired and at 300dpi.
So basically if you want super clean artwork (like we do) then please use a vector format rather than a raster one. You can still use Raster but make sure it is at least 300DPI and is at the exact size you want it already

Keep Going you got this...

Working with images can be confusing, but bearing these key facts in mind will eliminate much of the hassle and of course we’re always here to help or answer any questions.
