Unbeatable image quality.The quality of offset printing is reliable and you can always expect clean, distinct images or type without defects.Better color fidelity.This refers to both the accuracy of the colors and their balance within the design. Due to the ability to mix custom colors, offset printing will always get the colors just right.Ability to print on almost any kind of material,Whether you’re doing poster printing, vinyl printing, or large format printing, this printing process works on a wide variety of materials.Reduced costs for high volume printing.If you need a large amount of material printed, offset printing will save you money in the long run.However, offset printing may not be great for low-volume jobs, as it may cost more to invest in the equipment and material. Additionally, it is harder to fix an error if a typo on a plate is not caught early on. This may ruin a batch of printed materials, requiring you to start over again.

    When using digital printing machines, you can expect.A faster turnaround timeWithout the long setup process, a digitally printed project can be done more more quickly.Identical prints every time.Since there is no chance of imbalances in water and ink, you have a lower risk of variations between prints.Reduced costs for low amounts of prints.For low volume jobs, spending less on equipment and material by digitally printing the project will save you money.Making edits with ease. Changing information between batches can be done by simply making edits to the digital copy of the project.With that in mind, it’s important to remember that digital printing offers fewer materials you can print on. Additionally, because digital print jobs can’t exactly match colors, you may experience less color fidelity along with a slightly lower quality of the final prints.

Four color process printing is different from spot color printing – because while spot color takes specific PMS colors to directly print the design; Four color process uses Cyan Magenta Yellow K(Black) and blends different percentages of each of those 4 colors in order to give us different gradients within those colors. This sort of printing works really well when you are trying to print an image of someone’s face or a photograph because this type of printing allows you to get all of those different skin tones or varying shades within the images. Typically four color process printing is done on white or very light colored shirts.

• Six color Process Printing

Six Color Dry Offset Pail Printing Machine guarantees high printing accuracy with features such as automatic loading, flame treatment, pre-registration, auto unloading, etc. This Pail Printer includes centralized lubrication system, Micrometer lateral and radial plate cylinder adjustment. Complete vacuum system with pump that holds container on mandrels at neccessary position adds one of the important feature to our pail printing machine. This pail printer can printing about 800 impression per hour with a suitablity to print from 1 litre pail to 20 litres of pail.

• Eight Color Process Printing

This gives us the ability to separate jobs so that they print with better reproduction due to our ability to manage ink delivery. Line work and halftone screens can be split to separate print units for better print reproduction. Dense vivid colors are reproduced with pinpoint halftone dot accuracy. Using our dry dot proprietary screening technology, our graphics department creates separations that look like traditional 4/color process separations, but run clean on press limiting normal wet on wet ink contamination.  We can also split inkwells for those jobs that require smooth blending of several colors on the can. All of this is done on white base coated, clear brushed, or specialty base coated rigid aluminum cans.

 Better color separation flexibility (halftone screens and line copy of the same color can be split)

 Dry dot proprietary screening technology is applied in our Graphics Department which allows higher quality graphics to be reproduced

  Digital ablated plate making center located in Lebanon, Kentucky. Provides for fast revisions to graphics during new can artwork approval

 Split ink wells technology allows even more colors to be used on some jobs, and also allows for smooth blending of multi colored backgrounds

Instead the inked image is transferred (or offset) from the printing surface to a rubber blanket and then to the printing surface.

In offset-lithography, the paper does not come into direct contact with the printing plate. Instead, the image is transferred to a rubber roller. Lithography is used for medium and long print runs of products such as magazines, posters, packaging and books.

Offset printing is the dominant industrial printing technique – used for printing a wide range of products such as cards, stationery, leaflets, brochures, magazines, and books. It can also be used for packaging such as boxes or cartons. This page provides more information about this technique. For an overview of other printing processes, check this page.

The full name of the offset printing process is offset lithography. Both terms each describe part of the process:

Lithography is a printing process in which the image area and the non-image area co-exist on the same plane. That means the surface from which you print is completely flat. This is feasible because of a very useful chemical principle: offset printing ink is an oily substance, which means it repels water. If you can create a surface on which some parts contain a thin layer of water, those areas will repel ink. The image areas need be lipophilic (or oleophilic) – they accept ink – while the non-printing areas need to be hydrophilic – they are repellent to oil and receptive to water.

Some offset litho presses do not use a water-based dampening system but instead use printing plates on which a silicone layer repulses the ink. These are called dry offset or waterless offset presses.

Offset refers to the fact that the image is not transferred from a lithographic printing plate to a sheet of paper. Instead the inked image is transferred (or offset) from the printing surface to a rubber blanket and then to the printing surface. The process can be used to print on paper, cardboard, plastic or other materials, but these have to have a flat surface.

You can see an offset printer at work here. Because the plates and machine take time and extra money to set up and produce, offset printing is best for larger projects with a high distribution rate. However, even modern day digital printing cannot measure up to the customizable features of offset printing.

      In offset printing the matter to be printed is neither raised above the surface of the printing plate nor sunk below it . Instead, it is flush with the surface of the plate; thus offset is classified as a planography method of printing.

Offset printing, as a development of lithography, is based on the principle that water and grease do not mix, so that a greasy ink can be deposited on grease-treated printing areas of the plate, while nonprinting areas, which hold water, reject the ink. The offset plate is usually of zinc or aluminium or a combination of metals, with the surface treated to render it porous and then coated with a photosensitive material. Exposure to an image hardens the coating on printing areas; the coating on nonprinting areas is washed away, leaving wetted metal that will reject ink.

Modern offset printing is done on a press composed basically of three rotating cylinders: a plate cylinder, to which the metal plate is fastened; a blanket cylinder covered by a sheet of rubber; and an impression cylinder that presses the paper into contact with the blanket cylinder. The plate cylinder first comes in contact with a series of moistening rollers that deposit moisture in the granulations of the metal. A series of inking rollers then pass over the plate, and the ink is rejected by the water-holding areas and accepted by the greasy image. The inked image is transferred to the rubber blanket and is then offset to the paper travelling around the impression cylinder.

Our high quality direct print process uses up to 8 colours, providing label quality decoration with the economy of direct print. With our unique printing process we have the potential to replicate photographic quality, detailed designs. All separations and printing plates are produced in-house, giving total control, a quick turnaround and the ultimate flexibility.
