Low Cost Printing with Black Plate Technique

This printing techniques tips could be the cost savings on doing printing matters by choosing black plate optimizing. This technique tips only well-handed by the expert graphic designer or experienced printing companies to be tight on printing cost. When designing a piece for translation or other variety data, the main trick is to keep anything that changes on the black plate, or key plate only.

By doing this you will be able to keep the other three plates when you change over from one language to the other, and you will only have to pay the cost of the black plates. If you were to translate a flyer in 5 languages and you used this printing method, you would be paying the cost of 8 plates instead of 20. The more pages your design has, the more you save...

Printing Lamination – FAMOUS METHODS

A Lamination in printing business works is laminating of printing matters surfaces to make them look exclusively. The printing lamination could give you more fine results and durability of printing matters. It is widely used for finishing works in printing brochures, flyers, business cards, catalogs, etc.

Printing Inks - SPECIALTY TYPES


Metallic ink provides a distinctive look to a variety of print applications. The ink is produced by blending different types of metallic powders into the ink mixture, such as aluminum powder to create a silver appearance and bronze powder to create a gold appearance. Some metallic inks can nearly duplicate the look of foil on some applications without the need to purchase the additional equipment required for foil stamping.


Metallic ink is more challenging for the press operator to control than conventional ink. One reason for this is that the metallic powder blended into the ink mixture cannot be ground as fine as other pigments because the metallic ink will lose its luster. The larger particles create problems on the press, especially with the offset lithography process. To overcome some of the special print problems, some printers do a double hit (running the piece through the press a second time to apply another coat of ink to strengthen the coverage).

Most printers require an upcharge for the use of metallic ink on an application because the ink is more expensive to produce and makes the print job more time consuming. Metallic ink tends to have a much shorter shelf life than standard ink.

Magnetic ink
Magnetic ink is comprised of a petroleum-base ink blended with magnetic iron oxide particles. The magnetic iron oxide particles allow documents printed with this type of ink to be read and sorted by electronic scanning equipment. Checks are an example of a document printed with magnetic ink. The MICR (Magnetic Ink Character Recognition) number at the bottom of the check is the only portion of the check printed with the magnetic ink. The remaining copy on the check is printed with standard ink to ensure that no other printed area on the check interferes with the ability of the scanner to read the magnetic MICR number.

Non-porous Ink
Non-porous ink is used for printing on substrates, such as metal or plastic, that do not allow ink to be absorbed into the material. Because the printing surface of these materials is nonabsorbent, the ink dries solely through oxidation rather than absorption.

Fluorescent Ink
Fluorescent is another type of ink that can provide a distinctive look for a variety of print applications. Fluorescent ink colors are most often printed on labels, posters, and signs that are used for alerting people to hazards or attracting their attention to advertising pieces.
There are several points to consider when using fluorescent colors. The ink tends to fade quickly, so they should be kept out of direct sunlight. Because of their tendency to fade, fluorescent inks have a short shelf life. Another point to consider is that fluorescent ink is very transparent, so it may require a double hit (a second run through the press) in order to achieve the desired results. In spite of this potential problem, fluorescent ink is a good choice for creating emphasis and increased visibility.

Phosphorescent Ink
Applications printed with phosphorescent inks acquire a "glow in the dark" property after the phosphorescent area has been exposed to light. The length of time that an application will glow in the dark depends upon the ink ingredients and the length of time that the application is exposed to light. In some cases, a 10-30 minute exposure to light can yield an afterglow of up to 12 hours. The ingredients of phosphorescent ink are nontoxic and are free of radioactive additives. It is very useful for road signs, sporting goods, exit signs, safety products, toys, and novelty items.

Pearlescent Ink
Pearlescent ink is a specialty ink that is used to add highlights and depth to the printed area of an application. It is able to provide an almost 3-dimensional effect to some applications.

Edible Ink
Edible ink is used on print applications that may come into contact with food or the ink may be part of the food product and therefore it must be made of totally nontoxic ingredients. An example where edible inks are used would be in the monogramming found on some confectionery items. Because the inks are used on food items, they are strictly regulated by the government.

Scratch and Sniff Ink
Also known as a microencapsulated ink, scratch and sniff ink releases a fragrance when the microcapsules are broken. The scratch and sniff ink is commonly used in magazines for perfume advertisements. When the consumer scratches the surface of the designated area of the ad, the capsules are broken, releasing the fragrance.

Medical Device Ink
Ink used for printing on medical devices is made of nontoxic ingredients so that direct printing on noninvasive surgical and medical disposable items is possible.

Moisture Resistant Ink
Moisture resistant ink is most often used for different types of packaging or for applications that may be used outdoors.

Security Ink
There are a variety of inks that provide added security features to print applications. Some security inks allow documents to be created that are tamper proof, while the use of other types of security inks prevent documents from being copied. Security inks include the following varieties:
Coin Reactive, Bleeding, Erasable, Heat Reactive, Visible Infrared, Optically Variable, Pen Reactive, Penetrating, Photochromic, Solvent/Chemical Reactive, Thermochromic, Water Fugitive, UV Invisible Fluorescent

Desensitizing Ink
Desensitizing ink is a transparent ink that is applied to the face of CF (Coated Front) and/or CFB (Coated Front and Back) carbonless paper in order to deactivate the CF coating. The use of desensitizing ink is important when an application requires that handwritten or imprinted data not be transferred through the various pages of a carbonless form in specific areas.

Electronic Ink
Electronic ink can be transformed from bright white to dark and then back to bright white again with a small electrical charge. The ink consists of plastic microcapsules that contain both dark dye and white ink chips. The microcapsules are sandwiched between thin layers of flexible material, which substitutes for traditional paper. When an electrical charge is applied, some of the white chips float to the top of some capsules to create a white surface and in other capsules, the white chips remain at the bottom allowing the dark fluid to remain visible.

Printing Coating – FAMOUS TYPES


Coating of printing matters surfaces could provide the best surface properties and protection for printed surfaces. When coatings are applied as an off-line process over dry ink, they create a bold effect, but when applied as an on-line process, they create a much more subtle effect over ink that is still wet. Among the most popular coatings are overprint varnishes, aqueous coatings, UV coatings, and EB coatings.


Overprint Varnish
Applied during the printing process or as an off-line process, overprint varnish is much like a solvent-based ink. The different varieties are usually colorless, but sometimes they are tinted to achieve a desired effect. Varnish can be applied as an all-over coat or in spots to highlight a specific area of a printed piece.

Overprint varnish is available in glossy, dull, or satin finishes. Gloss varnish creates a smooth surface over the paper, filling in any voids or irregularities that may be on the surface. Dull varnish also fills in irregularities to form a smooth surface, but it diffuses light that reflects back to the eyes, which creates a dull appearance. A nearly 3-D effect can be created by applying gloss varnish to a subject and dull or satin varnish to the background. The subject will appear to jump off the page. In addition to applying varnish as a solid coat, it can also be printed as a halftone (series of dots) in order to provide subtle effects and to provide printed objects with an increased dimensional appearance. The effects that can be achieved are endless when using different combinations of varnish, paper, and ink.

Besides design effects, another important aspect of varnish is the protection it provides. A coating of varnish over a printed piece protects it from the wear and tear that is part of every day handling, allowing the document to remain intact for a longer period. An all-over coat of satin varnish will protect the printed surface without drawing attention to the fact that varnish was used for protection purposes.

A disadvantage of varnish is that many of them are solvent-based. Solvent-based means that they emit VOCs while they are being applied, which can be a health hazard for the press operator unless the proper safety precautions are followed. Another disadvantage is that varnishes tend to yellow over time if they are formulated with tung or linseed oil. Varnishes with alkyd formulations will not yellow, but they are not as glossy or as hard as tung or linseed oil.

The use of varnishes on print applications should be planned early in the design process. They should not be applied as an afterthought in order to try to cover-up a poor choice in paper, ink, or design.

Aqueous Coating
An aqueous coating is usually applied during the printing process and can be applied as an all-over coat or in patterns or spot coatings. Like varnishes, an aqueous coating offers protection for the printed document and provides numerous effects for print applications. Aqueous coatings are available in gloss, matte, and satin finishes. Among the advantages that aqueous coatings have over solvent-based varnishes is that they will not yellow over time and they are less toxic and emit fewer VOCs.

UV Coating
UV coatings come in a liquid or paste form and remain as a liquid or paste until exposed to ultraviolet light. The printed page is covered with the UV coating and is then exposed to the UV light, which causes photoinitiators within the coating to immediately react, creating a hard protective finish. Ingredients called monomers give the coating its gloss and hardness characteristics. UV coating, which is also known as an Energy Curable coating, provides the best surface properties and protection for printed surfaces. Some benefits of UV Coating include:
- Greater opacity, Color stability, Deeper and more vibrant colors and color tones.
- Sharper graphics, Higher gloss, Uniform surface to give labels a more vibrant look.
- Scuff resistance, Instantaneous curing, Allows for in-line die cutting.
- Chemical resistance, Better outdoor endurance.
- Environmentally safe - No VOCs (Volatile Organic Compounds) are produced.

EB Ink / Coating
Like UV inks/coatings, EB (Electron Beam) is an energy curable coating, but it is hardened with the use of a concentrated beam of high energy electrons. EB inks/coatings do not contain photoinitiators because the high energy electron beam is all that is necessary to cure the surface.

Other Coatings
Other types of coatings include clay coatings to add strength and gloss to paper, whitewash coatings which are used as a finish coat for such items as Kraft paper, and grease resistant coatings used on applications for industrial and scientific uses.

PANTONE Color Matching Sample


Pantone Matching System® uses 11 basic colors to achieve over 1000 color mixtures that are used by printers and art departments. The basic printing colors that are used are: yellow, warm red, rubine red, rhodamine red, purple, violet, reflex blue, process blue, green, black, and transparent white, which appears clear.


Each of the mixed colors are assigned a PMS number. The first number assigned for a mixed color is 100 and the numbering proceeds up from that point. The instructions for mixing the color are listed below the color swatch.

The mixing instructions include the number of parts of the specific base colors that are necessary to mix a particular color, as well as a percentage of the total volume for each of the colors that are required. For example, to mix the color, Pantone 198 (a red color), the mixing instructions are listed as follows:

6 parts (37.5%) Rubine Red
2 parts (12.5%) Yellow
8 parts (50%) Trans. White

By using the various ink formulas found in the swatch book, ink manufactures and printers can mix colors to exact specifications. Pantone also issues a digital color guide for electronic publishing which lists the color formulas in a format necessary for the colors to be displayed on a computer screen.

Note: Pantone Color Guides should be replaced after one year because the printed colors in the swatch book will shift or fade and will no longer be a true representation of the actual colors.
