Based in UK and USA, we’re the inventors of imagepac, the patented liquid photopolymer in a pouch that makes plate making faster, easier and better. With a passion for innovation we are constantly investing in new processes and products to improve the plate making process for flexography, Craft stamps and Office stamps.
Specialist and innovator in photopolymer since 2002

Profile Description

Photopolymer resin
This is where it all starts, we are one of the leading manufacturers of liquid photopolymer resin, from the softest Flexo 18 durometer corrugated grades, through to 50 durometer stamp grades and capping, right up to 90 durometer molding polymer. These are available in all packaging formats. Since 2004 we have been one of the few superclear or non-yellowing liquid photopolymer manufacturers.

We are specialist manufacturer of high performance 3D photopolymer resins. In 2015 we will be launching our brand new, affordable, LCD 3d Desktop printer. This, together with our range of resins, will completely change the 3D market as we know it! Cost is no longer an obstacle!

We take the photopolymer resin and pack it in three formats, imagepac flexo for the flexographic industry, imagepac superclear for craft use and imagepac xtra with integrated backing sheet for office stamps use. Invented in 2002, imagepac has revolutionized the world-wide stamp and plate making process. This is the fastest, simplest and most cost-efficient way of making plates. We now make millions of imagepac sachets in all sizes and formats.

We have designed and produced the unique imagebox Flexo, a complete exposure unit for our flexo liquid photopolymer in a bag, it is the fastest, lowest cost and simplest way to make a flexographic plate.
High Quality Clear Stamps

We take our own super clear imagepac sachets and make clear stamps with them, lots of them, in fact we are the largest private label stamp manufacturer. Manufacturing in both the USA and Europe, we turn your designs into stunning clear stamps. We will take care of everything from the moment you send us your artwork to delivery of your beautiful, crystal clear stamps, packed ready for sale. Visit our dedicated website at for more information.

Stampmaker kit
We then provide users with the amazing Stampmaker to expose their imagepac in and make their own custom designed stamps. Stampmaker is our best selling stamp machine, it’s low cost, simple and fast to use. We make two versions, imagepac business and imagepac craft stampmaker. Visit or

We move into a new 24,000 sqft building in Phoenix, AZ
We design and manufacture Costa 2 in America, the largest automatic stamp processing machine in the world. It is 120 ft long and processes over 70,000 stamps in a single shift.
We begin manufacturing custom stencils and ephemera.
We launch our Liquid Crystal 10 3D printer, the world’s first daylight hardening 3D printer, at TCT, UK
We are the first company in the world to sell a 3D printer using an LCD screen as its image source. Most experts from the 3D printing industry question the validity of using screens
We have a vision of where it can lead and start to invest heavily in R&D with a total of 13 scientists now working in 3D printing.

We purchase and move into a 35,000 sqft facility in Peterborough. At first, it seems that we have lots of room, but as we begin our journey into 3D printing the space fills up fast! We file our first 3D printing patent on using LCD screens.

Photocentric is awarded a UK Govt Innovate grant to develop a novel type of 3D printer based exposing daylight photopolymer using LCD screens.
We use our knowledge created from our first daylight activated stampmaker resins to make it work with LCD screens.

Over 70% of our turnover is now derived from our first patented product, imagepac.

We commercialise the concept as a home stamp making product for craft, imagepac daylight using the light from a desk lamp, combined with a negative printed on a home printer to make a printing plate. It is the first application of daylight cured photopolymer, other than for dental fillings, in the world.
Many years later this novel daylight chemistry will be the inspiration behind our 3D printing business.
We launch A8 size, now offering imagepac and imagepac xtra sachets in all sizes up to A3.

We are a finalist in the HSBC Start-Up Stars competition.
We automate the manufacture of imagepac by designing our first automatic filling and sealing machine.
We make a more sophisticated version of imagepac, which we call imagepac xtra. It has an integrated backing sheet (substrate) in the pack. It is harder to manufacture, but soon we learn how to automate the construction of this multi-layered package. Quality and reliability improve as we overcome initial sealing challenges and sales grow both at home and overseas.
We design our own exposure unit to make stamps using imagepac sachets and call it imagebox 1. It’s our first experience with the design and engineering of a machine. We react our first photopolymers.

Photocentric Ltd is formed in the summer of 2002 by Paul Holt in a small room in Peterborough. The idea behind the company is to commercialise a patent on pre-packaging photopolymer resin to make the process of making stamps easier and faster.
A few months later the first imagepac packs of photopolymer are made – they are not perfect, but are at least simple to use! It is the world’s first pre-packaged photopolymer printing plate.
At first, we make imagepac by folding plastic over on itself, sealing the edges, filling it with photopolymer, rolling the air bubbles out with a rolling pin and sealing the top- all by hand. It is a slow process and difficult to maintain quality.
We gradually improve it and steadily gain sales with UK business stamp makers, then after exhibiting at Paperworld in Frankfurt, Germany, interest grows quickly from around the world.
Our core values

We believe there is always a better way of making everything.
