Art File Requirment

We have a full time graphics department here at Umar Garments (Printing Division) . We use Adobe Illustrator and Adobe Photoshop to bring all of your artwork ideas to life. There are two state of the art, industry standard programs used for creating graphics.

Below is a breakdown of the acceptable art file types. More complex full-color images often require separation charges.


  • Vector graphic images – shapes created using paths instead of pixels
  • All fonts should be converted to outlines
  • embed any linked files
  • Illustrator can create very complex vector images that may end up being separated in Photoshop (additional fees may apply).

We prefer vector files created in Adobe Illustrator (ai, eps, pdf) with FONTS CONVERTED TO OUTLINES. Converting fonts to outlines is important because if you don’t and we do not have the font used to create the design, you design will open up with a different font than you used. Your design will be the best quality it can be and the print will be much cleaner than if it were just a Photoshop file.
Vector designs are created using paths instead of pixels. This means the artwork is very clean and it is easy to define the shapes that make up the design. Vector designs may also be scaled up or down with no loss in graphic quality.

Here is our Shirt logo as a vector file
In this image, you can see the paths that make up the logo.


  • Raster images – design elements created using pixels instead of paths 
  • Best for very complex graphics or photographic images 
  • Images must be created at a minimum of 300 dpi at print size 
  • Up-sampling web images does not make the graphic useable for screen print, a standard web image is only 72 dpi.

Raster files created in Adobe Photoshop (jpg, tif, gif, png, eps) at a minimum of 300 dpi at the final image size. These designs are made of pixels rather than paths. When zoomed in it is more difficult to see detail and where shapes begin and end. For this reason, our artist may have to recreate the image or clean it up. The end result may not be exact. 

Here is the same Shirt logo as a raster file. This could be a jpg or bmp file.When zoomed in, you can see the pixels that make up the logo. Notice how the lines are not as clearly defined.

If you don’t have your design already in one of these formats, don’t worry. We are able to scan, take a picture, make suggestions or take notes about your idea and bring it to life. We will send you a proof to your email and wait for approval before we do any printing of your product. 

Art for screen print is split out according to it’s individual color components in preparation for press set up. Art separation or color separation is the process in which we convert digital art files into screens for printing. There are different levels of complexity in the art we receive and this level is complexity is reflected in the process of conversion. We’ve defined these levels in four different groups. Send your art over for an assessment of complexity and potential art fees for separation. Below are the basic groupings - these groupings are guidelines. Final assessment is based on final art submitted.

  • One Color 
  • Spot Color 
  • Spot Color with Halftone 
  • Complex Spot Color 
  • Four Color Process 
  • Simulated Process 

There are no color separations when printing a one color job. The film and screens are identical to the art that we receive.

Spot color separation jobs are 100% vector files and usually are no more than three or four colors. The process of assigning pantone colors is straightforward and the number of colors is easy to count

Spot color with halftone separations are the next notch of difficulty after spot color. These designs are simple, but contain halftone shading and/or gradients

Complex spot color jobs have usually been created in Adobe Illustrator as vector files, but involve gradients, layers, embedded images, transparency or other effects. The level of difficulty can vary greatly within this category, which is why we ask that all art be submitted for quoting.

Four color process prints specially formulated inks in the colors of cyan, magenta, yellow & black to simulate how a regular ink jet printer would print. The inks are transparent, so this process can only be used when printing on white or, in certain cases, light garments. The images that call for this process are usually photographic or fall under the most difficult of the complex spot color realm. Often times, spot colors are added to the four color process ink print order for increased vibrance and saturation.

Simulated process is the screen print color separation solution for printing photographic or very complex, color rich graphics on colored garments. This process usually requires 8-11 screen colors and uses print techniques such as “wet-on-wet” printing to blend different spot colors into shades or other colors.
