You link it, we print it! – Putting Photos on T-Shirts using Simplomat and Spreadshirt API

“You link it, we print it!” is not our new slogan. But those of you who are with Spreadshirt for a while might remember one of the old slogans we had: “You think it, we print it!”. I did my own intepretation of that and wrote a Simplomat demo that shows what I mean.

The Simplomat is a Javascript abstraction layer and simple Javascript shirt designer for Spreadshirt API v1. It is open source and available at SourceForge. In my last blog post “Putting News Headlines on T-Shirts is Easy as Pie”, I already described how easy it is to use the Simplomat to put news headlines on shirts.

What does “You link it, we print it!” mean?

In my interpretation, “you link it” means, you give the Simplomat a Web URL that points to an arbitrary pixel image (gif, png, jpg). The image is ideally the result of your own work and reflects what you thought of (“You think it …”). The Simplomat will load that image automatically and render it on the selected product type. It also allows to rotate, zoom and move the added image.

“We print it” means that when you click on “buy now!”, the Simplomat will submit the created product with the design automatically to Spreadshirt using our API and after you got through the checkout, we will print the design on the t-shirt and send it to you. Isn’t that simple?

Putting News Headlines on T-Shirts is Easy as Pie

Two years ago, we had a project running with CNN where we created a special T-Shirt designer with CNN that allowed to order T-Shirts with CNN headlines with Spreadshirt. Since that day, lot’s of people looked at that and thought to themselves: “I want to have that too for my site!”.

Today, putting news headlines on t-shirts is easy as pie and becomes a commodity as our news headline on a shirt demo shows. In that demo we retrieve the CNN top stories, display them to the customers and allow them to put one headline on a t-shirt. They can also select a t-shirt color and size and order it via Spreadshirt.

All you need to create a similar Web application is our Spreadshirt API v1, the open source Simplomat from SourceForge and a news headline source, such as CNN’s top stories feed. In case you don’t want to use Spreadshirt’s default checkout, you also need to customize a Spreadshirt shop checkout to your needs.

But that’s basically it and it is really easy as pie. And different from most Adobe Flash based applications, it should even run on iPhone and iPad. Try it out!

Putting news headlines on t-shirts is just one use case the Simplomat is good for. Checkout what else you can do with it by going to our developer wiki’s Simplomat pages.

Twittershirts Demo updated

Checking the blogs I usually follow, I stumbled upon the blog post “Exciting Mashups: My Friends Mosaic, Handmade Spark, Liveplasma, Tesco” on Exciting Commerce. It talks about the My Friends Mosaic mashup that uses avatar images from twitter to render a picture of those followers to be printed on a shirt or similar.
By coincidence, last week, I wrote a blog post about my Twittershirts demo app that does the same thing using Spreadshirt API v1. I updated the demo, such that I also use the avatar images now instead of the plain user names, and can do pretty much the same thing as the my friends mosaic guys do. You can even order the shirt at Spreadshirt if you want.


Twittershirts Mass Customization Demo using Spreadshirt API v1 available

In my last blog posts, I told you about how to upload designs, create products and use the basket on Spreadshirt API v1.  To make it easier for you to use these features in your own application, I wrote a demo application that I called Twittershirts.

Twittershirts is a web application written in Java that shows how simple it is to write mass customization applications using Spreadshirt API v1. Twittershirts basically renders for a given twitter user id or name a followers cloud on a shirt and allows to buy this shirt at Spreadshirt. The used API features are:

  • Upload pixel designs to Spreadshirt using the API (twitter user’s follower cloud as png file),
  • Create new products (customer product) at Spreadshirt using the API,
  • Create basket and basket item at Spreadshirt using the API,
  • Retrieve basket checkout URL and redirect to Spreadshirt standard (marketplace) checkout.

You can try the application at The code is available on SourceForge at
You can also find this information on the Twittershirt application description page on our developer wiki.
