Are printed T-Shirts interesting enough for a post?

Leave a comment

Hmmm… A difficult question to answer? I’d guess that a quick straw poll would almost unanimously turn up a “No” verdict, but let’s see how we get on…

Before we bgein, if you haven’t already, reading my Why being a Web Developer is interesting… post may help provide a little context as this post broadly follows on from that one.

Printed T-Shirts?

I recently completed a website design for a Lancaster company, that specialises in printed and embroidered clothing in Lancaster, Morecambe, Heysham, Kendal and surrounding areas.

Whilst putting their site together, I was plunged into the heady world of printing on t-shirts, as well as bags, other clothing, ceramics, jigsaws and even cheese boards!!

Now let’s be clear, this is not the cheap shoddy t-shirt printing you used to get on Blackpool and Morecambe sea-fronts, which lasted all of three washes before flaking off.

Modern printing is of high quality, lasts wash after wash and some types can withstand temperatures of up to 80°C.

“Some types?”, do I hear you say? Ah yes, for as I now know, there are several methods of printing available dependent on your needs. The four I learnt about were screen printing, transfer printing, decorative film printing and sublimation.

For screen printing and sublimation, I’d suggest you follow the relavent links through to Wikipedia for a much better technical explanation than I could muster.

Transfer Printing

With transfer printing images are printed via a computer or scan onto a high quality transfer sheet. This is then heat-pressed onto the garment to produce a lasting print.

Prints can include full photographic images or any other design and can be applied to both light and dark garments.

Used for a single items upwards, this method is ideal for things like personalised gifts and photos on stag and hen party t-shirts.

Note, you can buy cheap kit versions of these for your home printer at PC World and the like, but I can tell you from experience that they don’t last and will quickly leave you with an unwearable t-shirt with a murky flaky picture in the middle of it.

Decorative Film Printing

This method is used for logos and text, such as individual names and numbers. Lettering is cut out from the decorative film and applied to the garment in up to 3 layers, allowing for a combination of colours and styles.

True to its name, the decorative film itself comes in a wide variety of colours and styles, such as flock, glitter, sparkle, leopard print and other special effects.

Ideal for names and numbers on personalised teamwear and sportswear such as football shirts and for company names on printed workwear.

Screen Printing

Designs for this method are completed on a computer and printed straight to the garment using silk screen printing.

Typically, this is used for volumes of 25+ identical garments and so is ideal for things like marketing promotions and giveaways.

Sublimation

Used for high quality full colour photographic images from a single item to large numbers, sublimation is ideal for white (only) clothing, as well as promotional items and personalised gifts such as mugs and mouse-mats.

In Conclusion…

Bored? Well, you can’t win them all. You probably won’t enjoy my forthcoming post on embroidery either!

Not Vacuum Sealed?

Leave a comment

Following on from my previous post (Why being a Web Developer is interesting…), I thought I’d write about something I learnt recently whilst developing a website for a local building and joinery contractor, who amongst other things, installs upvc double glazing.

During our discussions about his website design, he passed on a few interesting tit-bits relating to the building trade and this is one of them.

Not Vacuum Sealed?

The first revelation was that double glazing is not typically vacuum sealed. It is sealed with the intention of being air-tight however and although not a vacuum, the pressure inside will often be different to that outside.

As could be expected, the air that is sealed within the unit will have naturally occurring moisture within it, so why you might ask (and I did) do you not get condensation within the windows from the start?

Secret Silica Gel

The answer? The second revelation I received was that the brown (or black) metal strip that you can see inside your glazing running the length of the seal contains thousands of silica gel crystals. It is perforated with holes to allow the crystals to absorb water moisture from between the sealed panes.

This means that inevitable small breaks within the window’s seal can be tolerated up to the point at which the silica gel becomes saturated. After that, the windows are considered to be ‘blown’ and need repairing / replacing.

From reading further, I gathered that the length of time double glazing lasts depends on the quality of the seal, whether it is damaged during installation, whether water can freely drain from the frame so that it does not submerge the seal for any length of time, the amount of water moisture sealed in the unit to start with, the amount of silica gel used within the seal, the area in which you live and which direction your window faces.

Further Reading

Note, this information is recounted second-hand and although I have a passing interest, I don’t claim to be a scientist. If you want to know more or be sure of your facts before boasting in the pub, do a Google search or take a look at the following sites:

And for anyone who is interested in the green credentials of double glazing, this website discussion is worth your while:

And that’s it! You may have already known this or you may not care, but it was certainly news to me…
