Reverse printing is the process of printing on the back side of a clear substrate, sometimes referred to as subsurface printing, with a reverse image. In the process of manufacturing flexible packaging the print will be buried between the outside substrate and the rest of the structure, offering scuff and chemical resistance. When the outer substrate is mounted to the remainder of the structure, it will be right reading.Non-rigid packaging structures used to package and protect products. According to the Flexible Packaging Association, flexible packaging is any package or any part of a package whose shape can be readily changed. Common examples of flexible packaging are bags and pouches.

Flexographic printing is the method of printing on a web press using rubber or photopolymer plates with raised images. Rotogravure printing does not use plates, rather the image is etched directly onto a cylinder. It can be distinguished when looking through a loupe - it has teeth like marks around type and solids.

Glenroy uses solvent based, pigment inks.

Viscosity describes a fluids resistance to flow. In everyday terms, viscosity is the thickness. A liquid with a low viscosity, such as water, would be considered thin. A liquid with a high viscosity, such as honey, would be considered thick. Ink viscosity refers to this resistance of the ink.

Delta E is a color tolerance measurement. It is the measurement of a “sample” color compared to a “reference” color and uses a color difference equation to find the value. Glenroy uses the DE2000 equation for our measurements.

GMI, Graphic Measures International, monitors and measures the performance of packaging suppliers. They assist brand owners control the variables through print facility certification and scientific, repeatable measurement of global packaging.

Yes, Glenroy has gone through the GMI audit process and is a certified print packaging supplier.

An eyespot tracking path (or channel) is a pathway between the eyespots that the eyespot reader is tracking. Generally this pathway should be clear of obstructing design or text.
