Offset printing vs digital printing
Digital printing has brought more options and flexibility compared to traditional offset lithography. Digital printing eliminates printing plates and allows images to be directly fed from a computer to the printer. It has faster turnaround, allows for easy image editing, and is more cost effective for low volume prints. However, offset lithography still provides higher image quality and is better suited for high volume bulk printing. This article explains the key differences between digital and offset printing processes, their advantages and disadvantages.
Computer to Plate - Presentation
Computer to plate (CTP) technology directly images printing plates using lasers rather than first exposing film. This eliminates film processing and improves image quality with less dot gain. CTP uses platesetters with flatbed, internal drum, or external drum designs to image plates. Common plate materials include aluminum and photopolymer plates. Thermal lasers and GLV technologies provide high-quality, high-speed imaging. CTP offers advantages like reduced time and errors, easier changes, and more efficient digital file storage compared to conventional film workflows. New advances are eliminating the plate entirely in some systems.
offset printing
Offset printing was invented in the early 20th century in response to increased demand for faster printing speeds. The lithographic printing method at the time could not produce enough copies quickly enough. The first offset printing machine was built in Germany by Kašpar Hermann, a US-German citizen, who also patented the principles of the rotary offset printing machine. Offset printing involves ink being transferred from an inked plate cylinder to a rubber blanket cylinder and then to the paper through an impression cylinder. It is now the most common commercial printing method and can print materials like newspapers, magazines, and brochures at high speeds with good quality at relatively low costs.

Digital Printing ppt by Sukhvir Sabharwal
Digital printing is a relatively new technology that uses inkjet printing to apply colorants directly onto fabric. It allows any design to be printed on fabrics like cotton, polyester, and silk. Before digital printing, fabrics must be pre-treated with chemicals to prepare them. During the process, fabric is fed through the printer and ink is applied in tiny droplets. It is then cured through heat and the printed fabric is washed and dried. Digital printing enables continuous-tone images and printing to edges but has higher costs for sampling and shorter runs due to the slow printing speed.
What is offset printing
This basic overview of offset printing discusses sheetfed and web presses, prepress, inks, substrates, finishing, common applications, and trends.
The printing processes
Screen printing uses stencils to transfer images onto surfaces through a fabric screen. The stencil blocks ink from passing through in some areas while allowing it in others to create the image. Carousel screen printing uses multiple screens on a rotating mechanism to print with different colors more quickly and efficiently. Screen printing is commonly used to apply graphics and logos to products. Photocopying uses a dry toner instead of liquid ink in a non-contact printing process, allowing images to be reproduced in different sizes. Gravure printing employs an engraved plate to hold ink which is applied to paper to create high-quality art and photography books. Offset lithography uses oil and gum to divide a smooth plate surface into ink-accepting and ink

Digital and offset printing are the two main types of professional printing. Digital printing prints directly from digital files onto paper without plates, while offset printing uses plates to transfer ink from a plate to a rubber blanket to paper. Offset is best for larger print runs due to lower per-unit costs, while digital is faster with on-demand printing and customization. The offset printing process involves pre-press work to create plates from digital files, running the plates through a printing press, and finishing steps like trimming, folding and binding. Proper file preparation for offset includes using CMYK color, high resolution images, correct bleed and trim settings.
Digital printing
Digital textile printing involves printing designs directly onto fabric from a computer without additional steps. It can print any design onto fabrics like cotton, polyester, and silk. The fabrics must be pre-treated to hold the ink better and achieve high quality. Common inks used are acid, disperse, and reactive inks for different fiber types. The printing process involves pre-treatment, design modification, printing with a digital textile printer, and finishing steps like steaming.

Ink and dampening solution in balance 1
The document discusses test forms from Fogra and Heidelberg that can help identify problems in print quality by highlighting issues and their causes. It describes how Fogra developed a dampening control test form that allows printers to check and correctly regulate dampening solution application in order to achieve stable printing conditions. The test procedure involves first setting solid colors using ink density, then reducing dampening to the point of smearing while maintaining full toning to find the ideal balance of ink and dampening solution.
Delamination in sheetfed offset printing
Delamination refers to the separation of layers in printing stock like paper or cardboard. It can be caused by issues during cutting, stacking, or unrolling of paper. Precautions like carefully cutting paper, discarding bottom sheets, and using wedges or probes gently can prevent delamination. For example, in one print shop delamination was traced to a mispositioned cutter bar damaging sheet edges, causing strips to roll up during processing. Identifying the problem sheet can help determine if the cause was cutting, stacking, or something earlier in the paper making process.
Global print markets to 2016

Etching involves using acid to etch a design onto a metal plate. Intaglio techniques such as engraving incise an image onto a surface. Linocut and woodcut similarly cut designs but into linoleum or wood blocks. Screen printing uses a stencil to push ink through a mesh. Photocopying and laser printing use photoconductive drums and charged toner. Inkjet printing shoots jets of ink directly onto paper. Desktop publishing involves layout of documents intended for print.
Printing processes
The document discusses several printing processes and their advantages and disadvantages:
1) Offset lithography allows for high quality printing on various papers and can print on both sides. However, it is susceptible to color variation.
2) Flexography is a high speed process but has difficulty reproducing fine detail and consistent color.
3) Gravure provides consistent color and works well on cheaper papers, but the printing plates and cylinders are expensive to produce. It is best for long print runs.
4) Screen printing is economical for short runs and stencils are easy to produce, but it has limited applications.

Printing method
This document provides an overview of different printing processes, including relief printing (letterpress and flexography), planographic printing (offset lithography), and digital printing. It focuses on describing relief printing and letterpress, the earliest forms of printing where the image areas are in relief and non-image areas are recessed. Letterpress uses movable metal type and engraved blocks to transfer ink directly from the printing surface to the substrate through pressure. The document also describes flexography, an evolution of relief printing that uses flexible rubber or plastic plates to print on substrates like packaging materials.
Multicolour offset principle
Multicolour offset printing uses a wet-on-wet process where ink is applied to the paper without drying between color units, allowing the ink layers to split and mix, creating new colors through a process called back-trapping.

Lecture 8 digital printing of textiles (condensed)
Digital printing of textiles is an emerging technology that offers several advantages over traditional analog printing methods. Digital printing uses electronic design files and inkjet printing heads rather than physical screens or rollers. It allows for mass customization, quick design changes, and reduced waste. While the technology is gaining ground in niche markets like sampling, wider adoption has been slowed by issues like printing speeds and the high costs of inks and printers needed for bulk production. Continued improvements may allow digital printing to compete with conventional rotary screen printing for medium-sized runs in the future.

Has inkjet really achieved offset quality?
From about the middle of last year, the consensus seemed to be that inkjet had finally attained the same quality as offset lithography or flexography. How has that consensus been reached when the areas that inkjet still finds difficult are things like large regions of mid-tone tints? You simply don’t see press vendors, or buyers, making such comparisons. Inkjet problem areas are mostly caused by non-uniformity at both the microscopic and macroscopic levels. Martin Bailey explores how these spatial variations can be remedied and discusses an emerging ISO Technical Specification (ISO TS 18621-21) that is designed to objectively characterise some of these types of variation.
Printing
Screen printing and digital printing are two common textile printing methods. Screen printing uses a woven mesh screen to support an ink-blocking stencil and applies ink through the open areas of the screen onto the fabric below. Digital printing uses inkjet printing technology to place micro-sized ink droplets onto fabric directly from a computer design file. Both methods allow for localized color application and flexible designs, while digital printing enables very small minimum runs due to not requiring prepared screens. Key factors in choosing a printing method include design requirements, cost, minimum order quantities, and the desired finish.

WP Presentation Printing Machines
The document discusses different types of textile printing machines - block, roller, stencil, and digital. It provides details on the printing process and advantages and disadvantages of each machine type. Block printing is the earliest method but is slow. Roller printing allows for large quantities but setup costs are high. Stencil printing is simple but design quality is limited. Digital printing provides high quality and flexibility but has low speeds and high ink costs. Printing machines have helped revolutionize the textile industry and increase production capabilities.
Printing
Printing techniques were summarized including:
1. Printing involves applying dyes or pigments locally to fabrics to create designs through techniques like screen printing and block printing.
2. Screen printing uses a mesh screen to block ink from transferring in some areas to create sharp-edged images, while block printing carves designs into wooden blocks.
3. Other techniques include discharge printing which dyes the whole fabric and then removes dye in a pattern, and resist printing which applies a dye-repelling substance before dyeing.
3D Printing Concrete Building Constructions
3D printing technology can be used to construct buildings by depositing layers of concrete or other materials in a process similar to inkjet printing. The "ink" used is a special concrete mixture containing Portland cement, aggregate, additives, and fibers. Large 3D printers either have a fixed structure and print modular pieces for assembly or use a flexible robotic arm to print entire structures on site in a single piece. The printing process involves converting a 3D CAD model into thin layers that are deposited one by one to build up the structure. 3D printed buildings offer advantages like speed of production, design flexibility, and reduced construction waste.
Digital printing asian dyer extended version)
Digital printing offers several advantages over conventional analog printing methods for textiles. It allows for mass customization and quick turnaround due to minimal press setup times. Digital printing can change color schemes or designs in real time during production. It also produces less waste and has a lower environmental impact than screen printing. However, digital printing has lower throughput than analog methods and higher costs for long runs. It also requires specially coated substrates and has limitations in ink color options and opacity.
Print based media production
Digital printing techniques allow printing directly from computer files without plates or complicated prepress, providing flexibility and quick turnaround. Desktop publishing (DTP) involves preparing materials on a computer for printing, including page layout, text editing, and file preparation. Inkjet printing uses tiny droplets of ink in various colors applied by printheads to create images on paper. Laser printing uses toner particles transferred via a photoconductive drum to produce high quality prints.

- 4. How Offset Printers Work? Step 1 Step 2 Step n What is the Process? .....
- 5. Making Printing Plates ● Printing Plates, in a plate-making system, are exposed to measures amount of laser light ● When exposed to light, a chemical reaction occurs that activates an ink-receptive coating on the printing plate. ● This results in the transfer of the digital image onto the plate.
- 6. The Process of Inking ● Sheet of paper is fed into the printing press. ● Ink is transferred to the printing plates through a series of rollers. ● Printing plates are dampened, first by the water rollers, then by the ink rollers. These rollers move the ink from the ink fountain onto the printing plates. ● The image area of the printing plate accepts ink from ink rollers. The water rollers help to keep ink off of the non- image areas. ● Each printing plate then transfers the image to a rubber blanket that in turn transfers the image to the paper.
- 7. Color and Registration Control ● Color and registration control are processes that are controlled by computers. ● As the press runs, a computer scans a set of registration marks that have been placed on the press sheet. ● The amount of ink that is released into the color units depends on how much ink is required to achieve a certain ink density on the press sheet.
- 8. Final Bindery ● Pressed sheets allowed to dry, and transported to the bindery for finishing. ● Then cut and folded into the appropriate configuration for the desired product ● Stitcher takes the folded press sheets and collates and binds them together by inserting stitches or staples. ● Finally, paper is trimmed into the deliverable sizes.
