What Is The Alternate Of Offset Printing?
There are several printing technologies available and each of them fits different end-use applications. The alternate of offset printing includes a variety of different types of printing techniques that businesses can explore to produce their printed materials.
While offset copying utilizes offset paper, offset plates, and offset printing press to create a wide range of final products for the packaging industry and beyond, while comparing offset and flexographic printing, digital offers a faster turnaround with data capability and the ability to copy metallic and Pantone colors.
Flexographic and gravure copying are also alternatives, each with its unique strengths in producing high-quality print projects like business cards and brochures. One of the main differences between digital printing and offset printing is the use of liquid ink in lithography and the absence of platters and machines in digital printing.
Each alternative printing process has its advantages and limitations, so businesses may want to evaluate their specific copying needs before choosing the right printing method for their project.
Offset printing
Offset printing also called offset lithography is commonly used for large or flat items such as folding cartons, corrugated packaging, and large labels used on packaging and retail displays.
In lithographic or offset printing, the picture is placed on an aluminum platter, which is subsequently moved to a rubber blanket for further processing. After copying the picture onto a surface, it can be sealed or varnished for enhanced protection and aesthetics.
Often used for:
- Rough-surfaced materials, such as cotton, canvas, and wood.
- Adaptable technique that may be applied to books, paper, stationery, and other items.
| Pros | Cons |
|---|---|
| Suitable for copying in small to large format sizes | Relatively expensive for shorter copy runs |
| Capable of handling high volumes of copying | Custom-made aluminum plates contribute to the cost |
| Provides high quality graphics | Setup fees are often required to produce the plate |
| Considered the quality standard in package copying | Customization, short runs, and versioning can be cost-prohibitive for most brands |
| Exceptionally accurate color-matching | |
| Offers a variety of post-print finishes like gloss coating or foil embellishment | |
| Provides a touch of luxury and quality copy. |
Digital printing
digital printing is a method that is growing rapidly for use in product packaging. Despite being more recent than flexo, offset, and gravure printing, digital printing is developing and getting better very quickly. Specifically, inkjet keeps being more widely used because of its superior quality, reduced operating costs, and faster speeds.
Often used for:
- Signage and posters
- Letters, menus, labels, and newsletters
| Pros | Cons |
|---|---|
| Quick and agile for low-volume copying, short run times, and smaller SKUs | It can only copy in CMYK (not RGB) using the PMS Color System |
| Fast setup, with no plates to deviation or images to change | Somewhat worse color and ink copy quality |
| Computerized method, leaving little room for human error | Extended runs are more expensive |
| More accuracy in proofing, editing, and last-minute design changes | White, blue, or black paper cannot be printed on by digital printers that use toner |
Flexographic
Flexographic, or “flexo” printing, has been the preferred method for producing flexible packaging and high-volume labels for food and beverage goods for several decades. Fittingly called for its adaptability, the design is laid out on a rubber-based relief plate that is pliable and coiled around a cylinder to facilitate simple and effective copying.
An anilox roller is a low-cost, high-speed image transfer device that consists of a metal or ceramic cylinder with tiny “cells” that transfer ink to a plate. The plate then contacts the surface. Flexography’s supporters frequently claim that high quality flexo quality can now rival deviation because the process has evolved to include more automation and better quality.
Often used for:
- Labeling and packaging.
- Anything that features repeating patterns, such as wrapping paper and wallpaper.
| Pros | Cons |
|---|---|
| Relatively cost-effective in very long copy runs | Serialization and other forms of unique codes are cost-prohibitive |
| Fewer copying constraints | Small volume jobs for products with many SKU or design variations are cost-prohibitive |
| Can copy in almost any shape or format | Low-cost flexographic copy providers often struggle to achieve crisp copy quality and smooth or accurate color gradients |
| Ideal for high-speed manufacturing lines | |
| Achieves high-quality copy image | |
| Potential for perfectly matched spot colors |
Gravure
Gravure printing engraves your design into metal cylinders. The copying machine gradually transfers ink to each cylinder, which has a designated color, to produce an excellent image. It is frequently used for food products with flexible packaging and is advised for intricate package designs.
Often used for:
- Labels, shrink sleeves, and cartons.
- Gravure printing is commonly employed in the production of magazines and catalogs.
| Pros | Cons |
|---|---|
| Superior image quality and durability | Expensive for low quantity copy jobs |
| Suitable for ultra-high volume copy jobs | Lengthy setup time and high setup costs |
| High speed and low running costs | Not suitable for jobs with frequent changes to graphics or text |
| Reliable service providers ensure quality | Digital copying may be a better choice for brands requiring versatility and smaller volumes |
