http://www.rupainks.com/ The Printing Ink is used to mark or decorate parts. It come in different chemical families to match the type of material to be printed (please consult the substrate compatibility chart for selection).Pad printing inks are “solvent-based” and require mixing with additives at the time of use. They typically dry to the touch in seconds although complete drying (cure) might take a substantially longer period of time.Climatic conditions will significantly affect the performance of any pad printing ink, please bear this in mind when planning the location of your pad printer. Always consult Federal, State and local regulations regarding proper handling, storage and disposal of inks.

Rotogravure Inks Rotogravure (roto or gravure for short) is a type of intaglio printing process, in that it involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a copper cylinder because, like offset and flexography, it uses a rotary printing press. The vast majority of gravure presses print on reels of paper, rather than sheets of paper. (Sheetfed gravure is a small, specialty market.)Rotary gravure presses are the fastest and widest presses in operation, printing everything from narrow labels to 12 feet (4 m)-wide rolls of vinyl flooring. Rotogravure Inks - Printing Process Gravure is an industrial printing process mainly used for the high-speed production of large print magazines and runs at a constant and top quality, such as in the printing of large numbers of magazines and mail order catalogs. Additional operations may be in-line with a gravure press, such as saddle stitching facilities for magazine/brochure work. Once a staple of newspaper photo features, the rotogravure process is still used for commercial printing of magazines, postcards, and corrugated (cardboard) product packaging. Other use for the gravure processes are in wallpapers and laminates for furniture where quality and consistency are desired. Gravure cylinders nowadays are typically engraved digitally by a diamond tipped or laser etching machine. On the gravure cylinder, the engraved image is composed of small recessed cells (or 'dots') that act as tiny wells. Their depth and size control the amount of ink that gets transferred to the substrate (paper or other material, such as plastic or foil) via a process of pressure, osmosis, and electrostatic pull. (A patented process called "Electrostatic Assist" is sometimes used to enhance ink transfer.) Gravure is capable of transferring more ink to the paper than other printing processes, gravure is noted for its remarkable density range (light to shadow) and hence is a process of choice for fine art and photography reproduction, though not typically as clean an image as that of sheet fed litho or web offset litho. Usage of Rotogravure Inks Gravure is widely used for long-run magazine printing in excess of 1 million copies. Gravure's major quality shortcoming is that all images, including type and "solids", are actually printed as dots, and the screen pattern of these dots is readily visible to the naked eye.

Flexo Inks
Flexography (often abbreviated to flexo) is a form of printing process which utilizes a flexible relief plate. It is basically an updated version of letterpress that can be used for printing on almost any type of substrate including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging (it is also well suited for printing large areas of solid colour).
A flexographic print is made by creating a positive mirrored master of the required image as a 3D relief in a rubber or polymer material. Flexographic plates can be created with analog and digital plate making processes. The image areas are raised above the non image areas on the rubber or polymer plate. The ink is transferred from the ink roll which is partially immerged in the ink tank. Then it transfers to the anilox roll (or meter roll) whose texture holds a specific amount of ink since it's covered with thousands of small wells or cups that enable it to meter ink to the printing plate in a uniform thickness evenly and quickly (the number of cells per linear inch can vary according to the type of print job and the quality required). To avoid getting a final product with a smudgy or lumpy look, it must be ensured that the amount of ink on the printing plate is not excessive. This is achieved by using a scraper, called a doctor blade. The doctor blade removes excess ink from the anilox roller before inking the printing plate. The substrate is finally sandwiched between the plate and the impression cylinder to transfer the image.
Flexography Products
Flexo has an advantage over lithography in that it can use a wider range of inks, water based rather than oil based inks, and is good at printing on a variety of different materials like plastic, foil, acetate film, brown paper, and other materials used in packaging. Typical products printed using flexography include brown corrugated boxes, flexible packaging including retail and shopping bags, food and hygiene bags and sacks, milk and beverage cartons, flexible plastics, self adhesive labels, disposable cups and containers, envelopes and wallpaper. A number of newspapers now eschew the more common offset lithography process in favor of flexo. Flexographic inks, like those used in gravure and unlike those used in lithography, generally have a low viscosity. This enables faster drying and, as a result, faster production, which results in lower costs.

Screen Inks - Printing Process

Screen printing is the most used printing inks technology today. Two types exist: rotary screen printing and flat (bed) screen printing. A blade squeezes the printing paste through openings in the screen onto the fabric. Line art and text may be printed onto the outer surfaces of a PCB by screen printing. When space permits, the screen print text can indicate component designators, switch setting requirements, test points, and other features helpful in assembling, testing, and servicing the circuit board. Screen printing is also known as the silk screen, or, in one sided PCBs, the red print. Later some digital printing solutions have been developed to substitute the traditional screen printing process. This technology allows printing variable data onto the PCB, including serialization and barcode information for traceability purposes. Also some manufacturers tend to coat their boards in a thin layer of micro-film used to keep electricity from escaping the conductivity of the wire-strips.

This means that the artists' renderings on transparent film can be exactly reproduced on the nylon screen coated with light sensitive (UV) emulsion. The light sensitive emulsion fills the entire screen and the transparent film upon which the artists sketch is laid upon the screen. And both are placed in the exposure unit. Where the light passes through the transparent film, the emulsion is exposed and hardens. Where the artists' markings on the film stop the light, the emulsion is NOT exposed and released upon washing, creating a stencil on the screen that exactly reproduces the artists' markings to the finest detail. The screen is then placed on top of almost any substrate, paper, glass, fabric, golf balls, etc. Ink is then placed across the top length of the screen. A squeegee (rubber blade) is used to spread the ink across the screen, over the stencil, and through the open mesh onto the paper/fabric below. The screen is lifted once the image has been transferred onto the paper/fabric, which is replaced with the next, unprinted, substrate. Colors are added layer by layer and each color requires a separate stencil on a separate screen. The screen can be re-used after cleaning.
