Printing machines

  1. 1. Printing MachinesPrinting machines are growing in large numbers in the industrial set up of the economy.Every industry is using printing techniques and processes for effective communication. Therewere revolutionary changes in the early 90s in the printing industry as it became a serviceindustry and now is very much flourishing. The popular printing techniques are Letter PressPrinting, one of the oldest technique, Offset Printing and recently introduced Digital Printing,which is getting a boom in the printing industry. Some of the most used printing machines arelabel printing machine, flexo printing machine, CD printing machine, etc. 1. Digital Printing MachineDigital Printing Machines have gained popularity for short tomedium run jobs requiring high quality, clarity and finer printing.These printers deliver vibrant image quality and allow up to 8color printing.These affordable and high performance machines arerevolutionizing the printing industry by providing cost-effectiveand fine printing solutions. Digital printing equipment ensure fastturnaround time because of on-demand services. The techniques allows print on demand forpublishing books and is ideally suited to publish small print run of posters and books. 2. Pad Printing MachinePad Printing Machine is a type of offset printing providing fast andhigh clarity printing. This technique of printing is one of the mostversatile and used to printing three-dimensional objects andcompound angles. Pad printer reigns supreme in industrial printingfor high quality and fine printing on various materials includingplastic, rubber, metal, ceramic. The printing speed and quality ofpad printing machines depends on the kind, thickness ofstock/paper, type of inks used and other operating conditions. Theplate is as important for pad printing as stylus for screen printing.Pad printing equipment prints the image that is etched on the plate that communicates withink cup that fill the etched image with ink, then image is transferred on the surface throughpad.PRINTING MACHINES Page 1
  2. 2. 3. Embossing MachineEmbossing Printing machines are used by the printing industry forfine printing on a number of products. These machines help tocreate a three-dimensional image or effect on different substrates.Embossing can be done on different materials including paper,textile, metals etc. Embossing machines are also used to enhancethe look of aluminium foils. The machines are equipped withembossing modes in order to accommodate different materials.Thermographic machines can also be used for the raise lettereffect. 4. Thermographic Printing MachineThermographic Printing Machines provide a raised lettering effect,as commonly seen in business cards and are widely used by thecommercial printing industry. These machines also provide a lessexpensive alternative to foil stamping, embossing or UV coating.Thermographic Printing ProcessThese machines take thermography resin powder, sprinkle it overwet ink and bake it. This allows the powder to stick to the printedareas. Excess powder on non image areas is removed off the paper/substrate before theheating process. The sheet is finally cooled after the heating process and the melted powderhardens into raised thermographic image. 5. Letterpress Printing MachineLetterpress Printing is all time triumphant printing technique thatcan attach sensuous and stirring quality to design & art andlavishes vivid quality & nostalgic feeling that can not be capturedby other techniques. Letterpress Machine is also known as relief ortypographic printing machines, which are widely used to makecopies of images by repeated direct impression of an inked, raisedsurface against rolls or sheets of paper. The substances that areused in letterpress printing are identical to those used inlithography, include film developers and fixers, inks, and blanketand roller washes. The use of letterpress has been on the decline because of the advent ofmore advanced & efficient printing presses like the Offset Printing Machine, lithographicpress or the flexographic press. But after incorporation of photo polymer plates has paved theway for letterpress printing to revive its existence & hold sway even in 21st centuryPRINTING MACHINES Page 2
  3. 3. 6. Flexographic Printing MachineFlexographic Printing Machines produce high quality, finer andclear impressions on different substrates. These machines arepopular because of the simple operation and easy adaptation forthe use of water-based inks. Flexo printing is inexpensive and asimple form of printing method generally applied for packageprinting, moreover flexographic printer is good enough to produceexcellent quality impression on several different materials. Theseflexo printing machines are popularly used for printing onmaterials including plastic, paper, foils, acetate films, this is doneby use of rubber/plastic printing plates. Flexo printing machine hasa high speed printing process and makes use of fast-drying inks. Such printing machine canprint on a range of absorbent & non-absorbent materials and can print in continuous patterns. 7. Electrostatic Printing MachineElectrostatic Printing Machines use electrostatic forces to form theimage in powder or ink directly on the surface to be printed.Electrostatic printing machine has become so popular because ofhigh speed and cost effectiveness. Electrostatic printer isparticularly used by cartographers and publishers in order to printmaps & small books and ideal for small scale printing projects.Electrostatic printers are capable of producing constantly classicquality of print over a long period without making any changes tothe setting of the printers. Electrostatic printing machine isparticularly appropriate for printing multicolor topographic mapsand its quality is unparalleled. electrostatic printing machines that are reliable, inexpensiveand provides excellent resolution and printing quality, are required. 8. Screen Printing MachineScreen Printing Machine is one of the most versatile PrintingMachines, compatible to work on a number of surfaces includingtextiles, ceramics, metal, wood, paper, glass, and plastic. Screenprint machines have an edge over other print processes in the sensethat they can print on substrates of any shape, thickness and size.Screen printing machines are capable of offering exciting effectsthat can not be possible with other printing methods. This happensdue to broad range of dyes & inks which are five in types such assolvent, water, and solvent plastisol, water plastisol, and UVcurable. Screen printers are an ideal choice and an economicalway of printing when you need to produce nameplates, signs, labels, shirts, t-shirts, and otherarticles in large volumes.PRINTING MACHINES Page 3
  4. 4. 9. Offset Printing MachineOffset Printing Machine has been widely put to variousapplications. It is by far the most dominant form of commercialprinting technique, widely in use because of its unparalleledquality with respect to voluminous production and paper costs.These machines have a high set up cost but the printing process iscomparatively cheaper. Offset printing is also known as alithographic printing, provides vivid and sharper images and highvolume commercial printing that stands out offset printers fromothers though digital printing crept into the printing world.Flexography is still extant and used in label, envelop & ticketprinting but offset printing technology remains unbeatable. 10. Gravure Printing MachineGravure printing technique is used for long run printing withsharper, fine and clear images. It is generally used for high-volumeprinting of packaging, wallpaper, and giftwraps using fast-dryinginks. Although not widely used, gravure printing also findsapplication in printing magazines, greeting cards, and high-volumeadvertising print campaigns.Operations Required in a Gravure Printing Services:  Image Preparation  Cylinder Preparation  Printing  FinishingPRINTING MACHINES Page 4
