- Offset printing
Offset printing is a commonly used printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket, then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier on which the image to be printed obtains ink from ink rollers, while the non-printing area attracts a water-based film (called "fountain solution"), keeping the non-printing areas ink-free.
- Flexographic Print
As our most cost-effective imprint method, flexographic ink imprinting is available on many of our paper and plastic bags. Using a "flexible" photopolymer plate placed on a rotating drum, this method offers high-volume imprinting of your design. For intricate multi-color and four-color process imprinting using this method, contact our Design Centre custom team for more information.
PRINTING PROCESS - SOLID SPOT COLOR
PROGRAMS & FORMATS - Vector artwork preferred for velvet bags,nonwoven bags,cotton bags.. Click here for Artwork General Information.
TWO-COLOR IMPRINTS: For best results, artwork must be pre-approved by Bag Makers for printability. Colors must be separated by at least ½" of surrounding clear space to allow for color movement. Please note that some color movement will still occur. Multi-color imprinting is not available on some bags.
HALFTONES: For best results, artwork consisting of halftones must be pre-approved. A 30-line screen must be used with color percentages no less than 20% or greater than 60%. See example below. Files that contain gradients or blends will need alterations for optimum printing quality.
- Photogravure Print(Intaglio print or copper plate print )
Bopp film print,laminated Nonwoven fabric
Photogravure is an intaglio printmaking or photo-mechanical process whereby a copper plate is coated with a light-sensitive gelatin tissue which had been exposed to a film positive, and then etched, resulting in a high quality intaglio print that can reproduce the detail and continuous tones of a photograph.
PRINTING PROCESS - CMYK or Patone color
First print artwork on Bopp film,then coat the film with Nonwoven fabric.
Silk Screen Print
By injecting an ink through a fine mesh screen, your design is reproduced in clarity directly on each bag. For close registration on multi-color designs, use our ColorVista Print Technology for best results.

FONTS: -Minimum Size - 16 points and 2 point lines. Convert to outlines/paths/curves within your program. Thin serif font styles are not recommended.
MULTI-COLOR IMPRINTS: Color registration requirements exist and must be pre-approved. Please note that some color movement will still occur.
HALFTONES: Artwork must be pre-approved. Available on select bags.
- Hot stamping
Hot stampingis a dry printing method in which a heated die and foil are used to apply graphics to a surface. This is one method of security printing.
Hot stamping is a straightforward process:
1.A die is mounted and heated,
2.Foil is positioned above the material to be imprinted,
3.A combination of heat, dwell time, pressure and stripping time control the quality of the stamp.
Foil stamping is environmentally friendly due to it being a dry process. It does not use solvents or inks and does not create any harmful vapors.
Embroideryis the art of decorating fabric or other materials with needle and thread or yarn. Embroidery may also incorporate other materials such as metal strips, pearls, beads, quills, and sequins.
Embossing is typically accomplished by applying heat and pressure with male and female dies, usually made of copper or brass, that fit together and squeeze the fibers of the substrate. The combination of pressure and heat raises the level of the image higher than the substrate, while "ironing" it to make it smooth. In printing this is accomplished on a letterpress.
"Debossing" is similar to embossing, but recesses the design rather than raising it.
- Thermal transfer
Thermal transfer is when a specialized printer melts wax within its print-heads and uses it to print a design or text onto paper.
Thermal transfer is preferred over direct thermal printing on surfaces that are heat sensitive or when higher durability of printed matter (especially against heat) is desired.
Please Note: Our imprinting processes operate in a post-production environment in which imprinting takes place on a bag which is already constructed. This means that some restrictions — such as a fold or a gusset in the bag — may impact its printability and available imprint area. In addition, because colors in a multi-color design are imprinted individually, a space requirement between these colors is necessary for best results. ColorVista is not subject to this space requirement.
