Differentvariations of presses, plates, and inks are used for different run lengths and substrate requirements. For example, some presses may print millions of copies of a magazine. Other presses may print 250 large sheets that will be folded to make multi-page brochures.

Web Press: These printers automatically feed wide rolls of paper from one ink station to another until the appropriate about of ink is applied to each page. Web presses are typically used to print 10,000 or more copies of multi-page documents such as magazines, books, and catalogs.

In coldset web offset, the ink is fixed by absorption into the paper.

In heatset web offset, ink is fixed by absorption into the paper plus evaporation at high temperatures. Heatset web offset presses are four to five times faster than sheetfed presses and typically include inline folding equipment.

Sheetfed Press: This type of offset printing equipment feeds flat pre-cut sheets through the press. Speeds range from 5,000 to 20,000 sheets per hour. Sheetfed presses can handle a wider range of substrate types and thicknesses than web presses. Smaller sheetfed presses can handle papers as small as 4 x 6 inches. Larger presses can handle sheets up to 40 in. x 26 in.

A Perfecting Press can print on both sides of the paper automatically. All web presses are perfecting presses. But not all sheetfed presses are built to print on both sides automatically.

For years, a photo-engraving process exposed color-separated films onto photosensitive plates. Today, computer-to-plate (CTP) systems use digitally controlled laser engraving systems to etch the imaging data from digital files onto aluminum plates.

The prepress process for offset printing often includes more elaborate proofing methods, such as imposition proofs that enable buyers to check that all of the pages of a published magazine will appear in the desired sequence.

Formulations: Some offset inks use plant-derived oils such as soya oil or linseed oil to carry the pigment. Other inks use water-repellant fluids made with synthetic chemical mixtures. .

Special Properties: Some offset inks are formulated to change the performance of the ink on the paper. For instance, prints can be made with such as color-changing (thermochromatic) inks, metallic inks, magnetic inks, or UV-curing inks. .

With correctly formulated UV-LED inks and the proper UV-LED curing units, sheetfed offset presses can print on paperboards for packaging, non-porous synthetic sheets, foil-laminated sheets, plastic sheets, and a greater range of card and label stocks.

Thanks to innovations in offset inks and substrates, offset printing can print on a wide range of smooth and textured papers, paperboards, tear-resistant synthetic papers, and various plastics used in gift cards, bags, packaging, and envelopes. Some of the specialty materials available for offset printing include security papers, carbonless papers for business forms, and metal-laminated papers with silver and gold foils.

Web offset presses primarily print on the inexpensive coated and uncoated papers needed to control the costs of high volumes of books, manuals, magazines, and catalogs But these papers must be strong enough to withstand roll-to-roll high-speed printing. Most of the specialty materials are designed for use on sheetfed presses.

Finishing equipment includes devices for trimming and cutting the paper, or folding, binding, hole-punching, varnishing, laminating, or die-cutting printed sheets. Some printed sheets may be foil stamped, perforated, embossed, glued, or inserted into envelopes for mailing. Some finishing equipment makes it possible to apply clear UV-curable inks for added durability or decorative effects.

Offset printing offers several advantages that make it a preferred choice for many printing projects, especially when high quality and large quantities are essential. Here are some key advantages of offset printing:

In essence, offset printing's exceptional quality, cost-effectiveness for larger quantities, and adaptability to various materials and finishes make it a top choice for both business and creative printing projects.

As digital printing technologies have improved, so has the efficiency of offset printing. Manufacturers of offset printing equipment have developed prepress processes, software, and consumables that enable offset presses to produce more fast-turnaround, shorter-run print jobs.

Press manufacturers such as Heidelberg are developing systems that allow more steps in the offset printing and finishing process to be handled without any intervention by a human press operator.

Package is to depict the product as well as it preserves it. When one looks at the product, one expects to see the image of it. As the product comes to the fore in the printed packages, quality of the print also gains significance. To get an image of the product as real-looking as possible will also indicate the quality of the packaging of the product. To this end, in this study, various printings were carried out with the offset printing machine Heidelberg SM 52, using 300 g/m2 Norm print cardboard, 300 g/m2 SBS carton, 210 g/m2 Reno De Medici R.N. cardboard and 360 g/m2 kraft cardboard. In these printings we used ink from TOYO Ink Hy Unity NEO ERP series. A test print page was prepared by using ECI2002 test scale and the L*a*b* values of the prints were measured with TECHKON SpektroDens spektrofotometer. The color gamut ICC profiles were obtained in the Profilemaker program upon having the scales read by the scale spectal reading device i1io. Then the sizes of the color gamut were measured by using the Chromix Color Think Pro 3.0 program. This way, in the offset printed product packages, the proximity of the printings conducted on different cardboards to the real image and how much space the printed product occupies in the visible color gamut were dealt with in a comparative fashion. At the end these applications, the color gamut of the compared cardboards were extracted and the particular cardboard having the image closest to the real one is identified.
