Transcript of Digital Printing

Pros Cons Allows for accurate and high-quality printing.

Cost effective as cartridges can be refilled Colour limitations that don't produce optimal quality colour images

Require maintenance often as the thermal print head is susceptible to damage.

Requires heat resistant paper Digital Printing James and Nick How it All Started Photo: http://en.wikipedia.org/wiki/File:Papiermuseum_Basel_2008_(4).jpg How it All Started Cylinder seals (pictured below) used to print onto clay tablets The first records of printing date back to 3000 BC Photo: http://en.wikipedia.org/wiki/File:Cylinder_seal_Shamash_Louvre_AO9132.jpg Photo: http://www.dphotographer.co.uk/users/9038/thm1024/dsc_0554.jpg The History of Printing An example of what Block Printing looks like on a finished product This press was able to print 1,600 pages more per day then the pervious method of printing ‘Typographic Block Printing’ Photo: http://happypress.org/wp-content/uploads/2012/07/gutenbergpress.jpg

Jump started with the further development of ‘the computer’ in early 2000’s.

Replacing printing plates with digital images created on computers

A variety of media all produced from a digital based image Photo: http://carrietaphoto.files.wordpress.com/2010/08/printers_laser_printer1.jpg Stages of Printing The first stage in digital printing is the creation of the final product. Either from a camera, document or other method of creation. http://willkelly.org/wp-content/uploads/2012/02/Mac_WordIcon_web.jpeg http://blog.wanken.com/wp-content/uploads/2012/03/canon-5d-mk3-041.jpg These images/documents are then edited and prepped for print Laser Print Laser or Inkjet Whats the difference? I'm glad you asked Inkjet Creates a digital image by propelling droplets of ink onto paper. The following video will show you how the thermal inkjet printer works. There are two main technologies in contemporary inkjet printers Continuous Inkjet Printing Drop on Demand Inkjet Printing In this inkjet technology, ink is directed from a pump into one or more small nozzles, where it is then ejected into a continuous stream of drops. http://www-mat.ee.tu-berlin.de/research/inkjet/scheme2.gif The stream pass through a set of electrodes which impart a charge onto each drop. These charged drops are then pass through deflection plate which use an electrostatic field to remove dots that are not needed which are then recycled. Pros Cons High speed inkjet printing

High drop velocity

Use inks based on volatile solvents, allowing for rapid drying and aiding adhesion on many substrates.

Recycles ink that is not used Relatively low print resolution

Very high maintenance

Inkjet printers tend to clog if not used regularly Thermal Inkjet Piezoelectric Inkjet Types of DOD Inkjet Printing Steps of laser Printing Raster image processing Charging Exposing Developing Transferring Fusing Cleaning INKJET Vs. LASER http://bucarotechelp.com/computers/images/thermal.gif http://www.imaging.org/ist/resources/tutorials/images/inkjet_printer_fig2.gif Products That Come From Laser Printing Books
Food/Beverage Products
-Cans, wrappers etc. Information loads revived from computers is faster then inkjet printers, as it has to run smoothly for no misalliances of the ink. This video briefly explains how it all works. http://l.yimg.com/ea/img/-/121206/dark_knight_rises_best_worst_movie_posters_2012_18c073v-18c0796.jpg?x=400&q=80&n=1&sig=AcXAEGIm9OmCjsA5V7v5Mg-- Conventional Laser Printer Industrial Laser Printer http://i.dell.com/sites/content/business/smb/sb360/en/PublishingImages/dell-5530dn.jpg http://www.getprice.com.au/images/uploadimg/647/_2_CAN6630_0.jpg Digital printing helps add value to information for consumers http://www.hp.com/hpinfo/newsroom/press_kits/2009/GSBatPrint09/images/HPIndigo7000.jpg Comparisons between INKJET & LASER Users adopt digital printing for one of two reasons To communicate with consumers in new ways

Users can print quality products at lower cost Inkjet printers are cheaper; although ink is cheaper for laser per usage

Toners (used in laser printing) last alot longer then inkjet cartridges

Inkjet printers can work in-effectively if not used regularly

Running costs of an inkjet printer exceed those of a laser printer Consumers & Users Movement to smaller volume, high added value products and services

A decrease in the proportion of product value derived from manufacturing

An increase in the proportion of product value derived from service

It requires greater commitment to customer service

It allows the supplier to provide higher added value for any product or service Facts and Benefits of Digital Printing Digital printing does not require expensive metal plates to print from

Variable data: form of printing where elements such as text, graphics and images may be changed from one printed piece to the next.

smaller jobs are suitable for digital printers and cost effective

The ability to operate is simple, non-printing companies may easily adopt it in their workplace and that can result in a change in the industry structure

Digital printing converts a file directly into a printed product, hence the generic term ‘computer-to-press’

Digital print encourages and allows the change of workflow since it is one of the computer-to-plate (CPT) technology

30 pages per minute is considered fast, and many inexpensive consumer printers are far slower than that Main market sectors for digital printing Financial services
Public sector
Utilities Thanks for Watching The Indigo 7000 THE HOLLY GRAIL OF PRINTERS http://3dprintingindustry.com/wp-content/uploads/2012/12/2.3D-Drucker_VX200_Person.jpg Prints 120 high-quality four-colour A4-sizes pages per minute, 2 per second.


240 ppm monochrome or two-colour, 4 per second

'targeted at customers with average monthly volumes in excess of 1 million pages'

1,800 sheet capacity trays http://www.hp.com/hpinfo/newsroom/press_kits/2009/GSBatPrint09/HP_Indigo_7000_Digital_Press_FS.pdf What does it look like?
How big is it? Scaling this printer next to a Tyrannosaurs Rex, just to give you an idea on how large this printer really is. http://global.fncstatic.com/static/managed/img/Scitech/Blame%20Barney%203.jpg
