Flexographic printing is direct impression print process using a photo-polymer, flexible relief plate to carry ink to numerous substrates i.e. paper, corrugated, film and others. It is a respected process for high quality and speed. Presses are equipped with multiple process print stations, die cutting, ultra violet curing systems, waste processing, rewinding and more.
Modern printing methods such as toner and ink-jet printing are known as digital printing. Digital printing has a higher cost per page than more traditional flexo printing, but this price is usually offset by avoiding the cost of making printing plates and labor for set up. It also allows for on-demand printing, short turnaround time, and even modifications of the image (variable data).
Your label dimensions include (but is not limited to) the width, length, corner radius, and position and diameter of interior cuts, orientation to the roll, or sheet. See diagram for the standard method of measuring labels and rolls.
From foils to static clings, there are hundreds of label materials to choose from. When deciding which material to use, consider intended use, life span, surface and application method.
Copy is text and/or design printed on the label. The orientation of the copy to the label width, length and roll or sheet, is very important.
Colors and Color Breaks
Color break is how the elements of a label are printed. Photographs are almost always color broken as CMYK (cyan, magenta, yellow and black). Also known as "4 color process" or "4cp". The combination of the process colors, in varying percentages, can create almost any color. Alternatively, logos and text are usually color broken to print in PMS (Pantone Matching System®) colors. PMS colors print as one color, also referred to as "spot" colors. Use PMS swatch books for reference only. Colors look different on label stocks such as films, fluorescents, and foils.
A protective coating is recommended if the label is exposed to chemicals, moisture, extreme temperatures, or frequent contact by human hands. Types of protective coatings include UV/water-based varnished and film lamination.
“REWIND” or “UNWIND” Direction
A label rewind direction has three basic elements:
1.) How the label feeds off the roll; inside or outside.
2.) The direction of the label dimensions as it comes off the roll; width and length.
3.) The direction of the text and image on the labels. This is most important for machine application.
