In the world of screen printing, it is nearly impossible to print a gradient by laying down more than one ink color on one screen. However, the effect of gradient coloring can be achieved by playing a simple trick on the human eye using tinting or halftone screening.
This technique uses a series of dots that vary in size, spacing, or shape to simulate one continuous tone. Using dots varying in color allows for the recreation of virtually any shade of color by using multiple screens rotated in relation to each other as shown in the diagram below.
There are several definitions that affect the quality of the final output in halftone screening. The number of dots per linear inch is perhaps the most important factor. The standard resolution in screen printing is 45-60 linear pixels per inch (lpi). The angle and ratio of dots to white background are also factored in. Another key factor is the shape of the dots (elliptical, round, square, ect..) as seen in the above example. All of these are key contributors to the final product.
Using this tinting method, we are able to create stunning reproductions of brands, logos, images, and colors while limiting lead time and labor costs. This allows us to efficiently provide a high quality barrier cover at an affordable price .
