  • Graphics feature color gradients that are uniform and seamless.

Cons

  • It is only compatible with oil-based inks. These solvent-based produce significant quantities of volatile organic compounds.
  • More waste is produced during setup. A manufacturer must run several units through the machine. They do this before the print quality reaches a suitable standard. It increases with the number of colors.
  • Suitable only for malleable, lightweight substances such as paperboard and paper
  • The complex setup means costs for small volumes and MOQs are higher.

Inks for Lithography Ink Packaging

A surface is treated with nitric acid and gum Arabic solution for printing. The image zone is grease-responsive, while non-printing areas are water-receptive. However, this does not affect the outer printing layer. It remains wet due to applying oil-based pigment onto the surface using a charged roller.

2. Digital Printing

Digital printing is a popular technique for use in product packaging. Digital printing, in contrast to offset, flexo, and gravure, is a relatively recent technology. This direct printing method uses a digital laser or ink-jet printer. It imprints the desired information directly onto the packaging.

Digital printing is an economical choice for small print runs because of the absence of the need for a mechanical setup. Furthermore, it has full-color printing (CMYK) capability. It provides you with unparalleled versatility when it comes to designing artwork. And because everything is digital, last-minute adjustments to the artwork are easy to make.

This printing method is most effective for flexible packaging. It is used in corrugated and folding cartons when applied to film.

Digital Printing

  • The cost per unit is excessively costly.
  • Do not provide an excessive number of coating options in comparison to litho.
  • Digital printing incurs a more significant expense than alternative methods when applied to orders of considerable volume.

3. Flexography

Flexo printing is another term for flexographic printing. This technique prints on plastic, paper, and other materials. Cylinders roll around flexible plates to do the printing. You can personalize these plates with your artwork and spin them quickly by printing directly on the packaging.

Flexography has improved over the years with increased automation and quality. Users say it can now compete with offset in terms of high-quality printing.

Pros

  • Both oil and water ink toners were utilized.
  • Demand the least amount of tooling in comparison to offset.
  • Comparatively affordable price.

Cons

  • Failure to ensure a seamless color change during printing may lead to printing issues.
  • It has slightly lower printing quality when compared to Litho.
  • Unable to deliver a convincing duplicate of the image quality.

Best Inks for Flexography Printing

  • Water-based ink

Water-based inks are composed of pigment and water. It adds various substances, such as defoamers and agents, that aid in adhesion and drying.

  • Oil-based Ink

Oil-based Inks comprise pigments and hydrocarbons used for printing designs onto the surface. It contains soy oil and mineral oil in substantial amounts.

  • Electrum beam and ultraviolet

Ultraviolet and electromagnetic (UV and EM) inks comprise pigments, photoinitiators, monomers, and polymers. These inks are widely used in the food packaging industry for circumferential material deformation.

  • Solvent-based ink

Ink derived from solvents consists of alcohols and acetates. Typical starting ratios comprised 10%-20% acetates and 80%-90% alcohols for coloring. Utilize solvent inks when imprinting plastic buying bags.

4. Screen Printing

Screen printing is commonly called silkscreen. It consists of an image design and ink passing through a screen; serigraphy is a form of stenciling. The stenciled fragment deposited ink on the opposite side to fabricate the image.

This inking procedure is compatible with various materials. It includes paper, fabric, metal, and glass because the printing surfaces need not be planar.

This printing method packaging is an excellent choice for businesses. It is effective for companies that use stock or prefabricated packaging. You can print promotional and marketing materials on them, including t-shirts and flasks. It is best for labels, promotional materials, and folding cartons.

Different Types Of Printing For Packaging
