Some companies may charge a fortune to review and prepare you custom art for print. But, if you look around, you can find screen printer companies that do not charge for having their art department make your design look fabulous.
You can expect a charge if your logo or art design needs a lot of work, but it should not be more than a couple of hundred dollars. Some companies will even let you see before and after designs that they have worked on. Determine for yourself if they seem like they are proud of the work that they do, or if they are trying to get work off the line as quickly as possible, even sacrificing quality to do so.
Remember that screen printing is an art. Even though the process is becoming more and more automated, you still need an artistic mind to look over your custom work and help you determine the best ideas for printing it. The best designs are printed after being diligently worked on and digitized by a competent art department. The screen printing industry generally hires the best designers for this job, so take advantage of their talent, input and ideas.
Custom art can also be applied by embroidery. Here, you are looking at many of the same issues. Make sure that your color scheme, design details and image size are exactly right to get the results that you are looking for. With embroidery, you will need to make sure that a rayon thread is used. Also, make sure that letters are not too small to read. Specify instructions like 3D embroidery, heavy visibility or fine line embroidery. Make sure that you and the artist are on the same page.
With both embroidery and screen printing, you should make sure that the clothing or accessories you are using are compatible with the options you have chosen. For example, slick fabrics may need to be heat pressed for screen printing to stick and not peel. This will have you end up with a much heavier, thicker appearance of the artwork. If that is not what you want, then you may want to look at other forms of apparel.
Embroidery is best when done on heavier fabrics. Thin fabrics can bunch up, or the heavy embroidery can pull down on the light fabric, making it look low quality, even if it is not. Select fabrics that are compatible with the results that you would like to see. Furthermore, select name brand custom clothing for a guaranteed high quality result.
