Sublimation Education

AN INTRODUCTION TO DYE SUBLIMATION

Sublimation printing is a system adopted in schools. We may not have the word EDUCATION in our company name but Mega have been supplying schools with Technology products since 1977. We were the first to introduce sublimation to schools in 2003. In essence sublimation allows students to reproduce four colour images in the surface of various different materials.

WHAT IS DYE SUBLIMATION PRINTING?

‘Sublimation’ is defined as turning a solid into a gas and back into a solid without any liquid stage. This allows the application of sublimation inks into a materials surface using a Heat Press to provide the required combination of heat, time and pressure. This combination causes the inks to be converted from a solid to a gaseous state enabling them to penetrate the surface so that a permanent, full colour image is formed. The colour penetrates the material giving a result which is long lasting, colourful and resistant to scratching. Dye Sublimation should not be confused with other dry laser processes that transfer the images to the surface of materials making them easy to scratch off. True Dye Sublimation uses wet ink technology.

WHAT ARE DYE SUBLIMATION INKS?

Dye Sublimation Inks are in essence a formulation of special coloured dyes suspended in liquids that can be passed through a digital ink jet printer.

WHAT MATERIALS CAN BE SUBLIMATION PRINTED?

Suitable materials are man-made polymers such as Polyester and PVC. These can be ‘hard’ such as a polyester coated sheet of aluminium or ceramic tiles or ‘soft’ such as polycotton textiles. During the heat press stage the pores of these polymers open to allow sublimation ink (now in a gaseous state) to enter. As the temperature drops the pores close leaving the now solid ink image as part of the polymer.

In an education environment printable materials fall into three distinctive categories

SUBLIMATION SHEET MATERIALS

These are varied but include polyester coated aluminium; PVC sheets; plastic sheets, polymer coated, and polycarbonates.

SUBLIMATION MATERIALS ALREADY ON-SITE AT SCHOOL

Various plastics including Foamex board, PVC (for vacuum forming), textiles containing polyester more than 50%

MINI ENTERPRISE PRODUCTS

Sublimation jigsaws, bags, ceramic tiles, ceramic mugs, business cards, coasters, place mats, mouse mats, tee and polo shirts, pencil cases, aprons, sunshades, book marks, money boxes, phone covers and key rings and many more.

All Sublimation materials tend to be white to enable true accurate colour reproduction. If you added an image to a coloured base the image would be distorted by the base sheet colour.

WHAT MATERIALS CANNOT BE SUBLIMATION PRINTED?

As dye Sublimation is always performed on a polyester, polymer or polymer coated item, materials such 100% cotton are not suitable as the natural fibres have no pores to open to accept the image. Cotton can be sublimated but the image will fade with a few washes making 50% polyester 50% cotton weave a required minimum. 100% Polyester will always produce deeper colours.

HOW DO YOU PRINT AN ITEM?

This is a digital printing system so you firstly select or create your colour image on a computer. Any picture from any software package will do - as long as it will print on a piece of paper it will be fine!

We exclusively sell the Virtuoso Sublimation Printers, this is the printer designed specifically for sublimation.

All Virtuoso machines supplied with:

  • Free downloadable Virtuoso Print Manager (VPM)
  • Free downloadable ICC Colour Profiles for Mac
  • Free access to CreativeStudio

The new Virtuoso SG 400 and 800 inkjet sublimation printers deliver dazzling HD photo-quality prints. CreativeStudio is Sawgrass' free innovative online design software and stock design library, developed to help creative designers quickly and easily produce transferable images. Available exclusively as part of the Virtuoso HD Product Decorating System, this powerful tool enables you to easily create great-looking designs from any Internet-connected computer.

Product Advantages:

  • The only desktop inkjet printer optimized for digital decorating and SubliJet-HD inks.
  • The first sublimation printer co-engineered with Ricoh.
  • Lowest start-up cost of any commercial product decorating technology.
  • Higher definition image reproduction with vibrant, true-to-life colours.
  • Faster throughput for greater productivity.

The image is printed on sublimation paper ‘mirror image’ and is then laid onto the sublimation material and secured with a little ‘heat tape’. The two are then placed in a Heat press for typically 1-2 minutes at a temperature between 160°- 200°c. The exact time and temperature depends on the material being used. At the end of the cycle the paper is removed to reveal a bright vibrant scratch resistant coloured image.

PRINTERS

Virtuoso is now the chosen printer for sublimation. The special high capacity inks mean no 'bulk feed ink system is needed' The new Virtuoso printers offered by Mega have very high print speeds, a self-cleaning print head and high ink dispersion rates to prevent ink blockages. They use print head technology with virtually no heat being generated which means the ink does not sublimate in the printer. 'Bubble Jet' printers from manufactures such as HP, Cannon and Lexmark heat the ink in the head to force droplets onto the paper. This means all these types of printers are unsuitable for use with sublimation inks that react to heat.

SUBLIMATION PAPER

If you used low cost photo copy paper too much of the ink would absorb into the paper itself and not enough would be 'Sublimated' into the material. Sublimation paper has a coating on the surface which effectively means the ink sits on the paper without ever thoroughly drying. For the Virtuoso printers we have a specially formulated paper which is quick drying but provides excellent colour saturation everytime. Customers printing very soft plastics should use the "Sublimation Special" paper which will not stick to heated soft plastics.

HEAT PRESS, MUG PRESS

The constant even pressure and variable temperature control make a Sublimation Heat Press essential. Mugs will obviously not fit in a flatbed press so a special Mug Press can be purchased.

COMBINING TECHNOLOGIES

Sublimation Printing can be used in conjunction with other manufacturing processes. For example; clear or white PVC sheet can be sublimated and then allowed to cool in the flat. The printed plastic can then be vacuum formed. A video resource is available from Mega which shows a vacuum forming tool being made on a laser cutter and the clear PVC being sublimated before it is vacuum formed to produce a colourful three dimensional light switch cover for a child’s room. Another example of sublimation printing and thermo-forming is with foam board. This can be printed and when it is still warm from the press formed into shapes using a simple press forming tool.

WHO IS USING SUBLIMATION?

In Schools and Colleges Sublimation is suitable for use in a wide range of areas. These include Graphic Products; Engineering; Product Design; Food Technology; Art and Design; Textiles and Enterprise.

COSTS

Printing costs are difficult to equate as it often depends on how often the system is used and therefore how many cleaning cycles and head cleans the printer performs. Best estimates however for a flood coat A4 image on an A4 printer are between 40p and 50p for both ink and paper, one third less for A3.

HOW RELIABLE ARE THE PRINT SYSTEMS?

The new Virtuoso printers used in conjunction with SubliJet sublimation inks are efficient and reliable, Sawgrass recommends, keeping your printer trouble free leave it powered on 24/7.

WHERE DO YOU BUY?

Mega Sublimation Printing is a division of Mega Electronics Ltd. Mega has been supplying schools for over 40 years with electronic teaching systems. A large part of the business has always been systems to enable customers to produce their own signs and labels; sublimation printing is one such system. Mega has been selling sublimation products to schools for five years and offers complete range of equipment and materials and most importantly a comprehensive level of training and support.
