Semester 1 highlights

As we come to the end of year, we also come to the end of the semester. It’s been a joy to have students back in the workshops. It’s been great to see so many students making the most of being back on campus, exploring new processes as much as possible. We’ve had students from across a range of subjects from Graphic design to Landscape Architecture, learning about digital printing and CAD Embroidery.

New Equipment: Over the summer, before the start of the semester, the Textile Digital Print facility acquired a new digital printer; Mimaki TX300. With this new machine students can now digitally print onto a wider range of fabrics, and most recently wallpaper; an exciting new addition!

New fabric options: The facility also added a selection of new materials for printing such as a range of organic and recycled fabrics. This is part of the facility’s, as well as the wider university’s, on-going commitment to becoming more environmentally sustainable. The facility has also added to it’s range, the option of printing onto alternative surfaces, such as Aluminium panels. Specially coated for print, these panels welcome a new type of material surface for printing at ECA.

Most importantly this past semester has seen our students create a range of new and engaging work. We can’t wait to see all our student’s again in 2022, and their amazing work!

Student Spotlight: Laura Miani Fernandez

Conceptual Bullet Proof Vest in Context

Over the course of the last two years, for her MFA project, Laura has been working on OJO! (oh hoh) ; a textile protest project that looks at Colombia’s ongoing civil war, and the ways textiles and design can be used as tools to spread awareness of this issue, both within local and international communities. A conflict that has lasted for decades, this project aims to encourage people to look harder, to challenge and ultimately become more consciously aware of the issues currently present in Colombia.

Within her project, Laura explores how textiles, and textile processes can highlight conflict, as well as how they can be used as a form of protest. Inspired by traditional techniques such as Mola; Colombian/Panamanian indigenous reverse appliqué textile technique, and Camouflage, Laura has designed and created a range of textiles that look to protect scared cultures, as well as those fighting to protect it and their lives.

Laura has explored, both at home and within ECA, screen printing, digital textiles and CAD Embroidery techniques. We love how inventive Laura’s been with combining techniques, in particular her experimentation with adding surface decoration to bullet proof materials, through CAD Embroidery and silk screen printing. Through access to the facilities at ECA, for her final showpiece, Laura created a conceptual bullet proof vest that combined and used the techniques mentioned above. You can see the final outcome of this in the photos above & below.

We know this project is just the start for Laura. We can’t wait to see where it takes you and how it grows with time. If you’re interested in Laura’s work, her concept of protest textiles please check out her website. There is a whole host of information on here, as well as a great short video she’s put together about her work.

Different types of Printing

When it comes to printing onto fabric, there are lots of available options, from traditional methods such as Block and Screen Printing to modern techniques like Digital and Sublimation Printing.  Each technique has it’s own unique aesthetic and characteristics, as well as pros and cons.

What method you choice to use will largely depend on fabric choice. In some cases you can combine techniques, to create interesting and dynamic textiles.

Here we will cover the main types of printing digitally:

Transfer Printing

This technique allows you to digitally print onto fabric, from home. Imagery is printed onto specialist paper, called Transfer paper, through either inkjet or laser print household printers. Once a design is printed onto the transfer paper, it is transferred onto fabric with a steam iron.

Transfer paper can be purchased online and in shops making it easily accessible. This printing method will leave a shiny film/surface to your fabric, and is not classed as a permanent method of printing, as it can crack, peel and fade with time.

Pros

  • Accessible printing method
  • No specialist equipment needed
  • Great for sampling/small runs
  • Easy to print and transfer

Cons

  • Leaves a shiny film/texture to the fabric
  • Single use transfers
  • Limited life span; peels, cracks and fades with time/washes
  • Limited print quality and resolution as well as colour range

Dye Sublimation

Sublimation printing is a sophisticated alternative to transfer printing. A multi-step process, this printing process is suitable for synthetic based fabrics.

Designs are first digitally printed onto thermal transfer paper called Dye Sublimation paper. This paper is then used to print onto fabric through the use of heat and pressure, permanently bonding the inks on paper to the fibres of the fabric. This step is usual done by using an industrial heat press. Once you’re fabric has been printed, it is set and ready to use. As this process uses dyes, the fabric retains it’s original characteristics.

Pros:

  • Digitally prints are permanent, colourfast & washable
  • Dye-based inks allow for a wider colour range and colour brightness
  • Soft handle and feel to fabric, with original fabric characteristics retained
  • No post-treatment required
  • Minimal ink and no water wastage

Cons:

  • Not for use on natural fabrics
  • Specialist equipment and dyes required

Reactive Printing

Reactive or digitally printing as we call it, is for digitally printing onto natural based fabrics.

This process uses Reactive dyes, which are suitable for printing onto both cellouse (plant) and protein (animal) based fibres. These dyes require fabric to be treated with a specific pre-treatment before printing. Pre-treated or coated fabric, is rolled and loaded onto a digital printer for printing. Imagery is printed when ink passes through the machine’s printer head, in a similar way to an inkjet printer. Once printed, ink is fixed to the fabric through a Steamer. This moist heat causes the inks to react and bond with the fabric. To complete the process, fabric is washed to remove the pre-treatment coating and any excess dye. Once washed, fabric is ready to use.

Pros:

  • Digitally prints are permanent, colourfast & washable
  • Dye-based inks allow for a wider colour range and colour brightness
  • Soft handle and feel to fabric, with original fabric characteristics retained
  • Inks penetrate fabrics’ extremely well
  • Minimal ink wastage

Cons

  • Not for use on synthetic fabrics, natural and pre-coated only
  • Fabric requires pre-and post-treatment
  • Specialist equipment and dyes required

Pigment Printing

Pigment printing allows you to print onto most fabric types, including natural and synthetic, making it a popular and versatile printing technique. Designs are printed onto fabric and are set to the fabric using a dry heat, usually through a heated roller or Heat Press machine.

Pros

  • Print onto a wide range of fabrics in a variety of weights
  • No fabric pre-treatment necessary
  • No water or specialized fixation, steaming or washing process required.

Cons

  • Pigments sit on top of a fabric’s surface rather then being embedded into the fibres.
  • Pigment binder leaves a coating on top of the fabric
  • Colour range not as wide as with dye-based inks

As you can see there is a wide range of digitally printing options available, some more accessible than others with their own unique pros and cons. Currently within ECA we offer Reactive and Sublimation digital printing. Whilst we don’t offer digital pigment or transfer printing, we can offer support and guidance with these techniques for anyone interested. Remember you can always get in touch by emailing textiles@ed.ac.uk to speak to one of our textile techniques.

Online Resources

As many continue their studies under tightened COVID restrictions, the importance of accessible online resources remains vital.

At the start of Semester 1 (2020), we set up a SharePoint site for Textile Digital printing resources, to act as an online resource/hub for UoE students and staff. Providing written, as well as visual guides on many of the processes and techniques, this site supplies up-to-date information on these resources. If digital print is something you are curious about and/or if you wish to find out specific information, e.g. what fabric options are available, then this is the place to go.

For anyone wishing to check out the site mentioned above, please click the following link: https://uoe.sharepoint.com/sites/TextileDigitalPrinting

Pleased be aware this site is only accessible to UoE student and staff as the site is help within the UoE Intranet.

Whilst workshops may currently be closed, please remember technician staff are still at hand and able to help you when and where they can, even if it’s just to talk through an idea! Among us we have a vast amount of experience and knowledge to share! Therefore if you come across something that interests you, online or say through the SharePoint site, make sure to get in touch to see how we can help.
