The Words That Sign Masters Use
We believe the more you know about sign making, the more you will appreciate the skills and capabilities of the sign masters at April Graphics. That is why we are providing you with a glossary of terms we use in our business.
You do not need to know the terms to order custom signage, but you may want to look up terms that puzzle you or seem particularly interesting.

PPI (pixels per inch): The number of pixels in a raster image that will occur in one line in the span of one inch. The higher the PPI, the greater the resolution.
Reflective Sheeting: Film with very small glass or glasslike bead materials encapsulated below its surface, creating the ability to bounce light back to their source, such as from a car headlight back to the driver.
Registered Trademark: A trademark that has been officially registered with the government by its owner. Indicated by the symbol ®.
Registration: In printing, the correct placement of the image to be printed on the substrate.
Resolution: In digital images, the number of pixels shown on a screen; the higher the number of pixels in a given space, the more precise the pictured image.
Sandblasting: A method for decorating sign substrates using a rubberized stencil of the artwork which is then sprayed with a pressurized stream of sand to etch the unprotected area.

Substrate: The material out of which the sign face is made. Wood, metal sheeting, paper and acrylic are some examples of sign substrates.
