In my experience, I’ve found that the best place to buy screen printing supplies is online. I’ve been doing screen printing for a while now, and I’ve tried a few different suppliers. The best one I have found so far is Screen Print Essentials Ltd. This site has a great range of screen printing consumables at good prices. What I like is that they have fast delivery options and free delivery for orders over £400 which is perfect for my business.
If you don’t want to buy online, you may find it hard to find screen printing supplies on the high street. Larger office supply stores or hobby shops may stock some items, but if you’re looking for a wide range of products and options, buying online is definitely your best bet. I also find that the prices of supplies online are usually cheaper too. Hope this helps.
