The official technical stuff from Printcolor
Printcolor 751 is a popular ink with trade pad printers because of its almost universal application for most substrates. Series 751 used with Printcolor HDi hardener will print a wide range of the common plastics including (but not limited to); pre-treated polyethylene (PE) and polypropylene (PP), polycarbonate and duro-plastics. Printcolor 751 with HDI hardener also gives excellent results on metals and coated or painted surfaces. In addition, you can mix Series 751 with Printcolor GL hardener to print durable, glossy images on glassware and ceramics. Printcolor 751 is formulated from epoxy resins with high chemical resistances and is designed for use on industrial and commercial products for internal (indoor) applications. Refer to the Technical Information and Series 751 MSDS documents for more details.
Printcolor 751 ink is a highly opaque, high gloss ink that is exceptional for its user friendly handling, and its excellent adhesion and durability on a wide range of substrates. This is the perfect ink for a start-up business, or for printers who just want a single, fuss-free ink that will print most jobs.
What we say about Printcolor 751
We looooooove 751! It’s just so easy to use, even for beginners, because it NEVER gives you issues with static or pot life, and it’ll produce a great print even if you run it a little bit too thick, or a little too thin. Printcolor 751 lets us get through the work without fuss regardless of whether we’re printing hand made wine glasses, cheap pens or chromed make-up brushes. Everyone should have a couple of cans on the shelf.
Hardener: addition ratio of 4:1 700-HDi hardener or 700-HDS hardener (plastics, metal)
Hardener: addition ratio of 20:1 up to maximum 10:1 700-GL hardener (glass and ceramics with heat curing)
Thinner: 700-017 thinner – addition ratio 10 – 15% by weight for open well

The good oil from our trade print room
- Without doubt the easiest pad printing ink to use – period. It’s happy being run thick or thin and NEVER gives static spiderweb problems. We find that running it a bit thicker often gives a great glossy print, but you may have to go a bit slower to allow the ink to fully transfer – air blowing on the pad helps with this.
- A bit of a problem solver, we’ve found that 750 will often stick when other inks won’t. On difficult substrates high temperature oven curing often helps to give better adhesion.
- Can bit slow to air dry especially over winter, so if you’re in a hurry hot air curing is a good idea to speed things along. In winter, 750 can take up to 3 days to air cure, and 1-2 days in summer depending on the weather. In our experience adhesion and wear resistance will continue to improve for several days even after that. In practice if you are air drying product allow at least 24 hours in summer and up to 48 hours in winter before packing and shipping or you risk damaging the print.
- Because it’s a slower ink system, you will often get better transfer by using a short pause at the front and air blowing on the pad to help with transfer. Multi colour printing can also benefit from air onto the product to dry the previous colour and prevent the next pad from picking up bits of the image, especially with large areas of solid colour.
- It’s very versatile; mix to a ratio of 4:1 with 700-HDi hardener for plastics. metals and most of coatings, or mix with 700-GL hardener at a ratio of 20:1 for printing ceramics and glassware. It’s the only ink on the market that we have seen to have a universal hardener system allowing you to change substrate compatibility, just by using a different hardener. An example of fantastic chemical engineering from the labs at Printcolor, and a very convenient innovation for us printers.
- Abrasion resistance of the final ink layer can be aided by adding 700-RCA additive on demanding applications like switches.

Why Use Printcolor Pad Printing Inks?
Well let me give you my take on the why, and you can make your own conclusion. We talk to a lot of printers about the getting right ink for their pad printing projects. And with good reason… The ink you use makes a world of difference to your work. With the right ink you can produce more, with greater consistency and quality, in less time and for less money.
Working too hard? Change ink… and change your business!
Clearly, with so much at stake, you want to choose wisely and the first thing you should know is that ink brands ARE different.
We often talk to people who are doing a tremendous amount of unnecessary and time-consuming work, not realising that their ink was making their whole production process problematic. They just thought that sometimes pad printing could be… well… difficult. Once we matched their project or application with the right ink for the job, efficiency (and profits!) went up immediately. And stress levels fell. Leading Swiss ink manufacturer Printcolor, has developed a wide range of high performance pad printing inks formulated to perform well in the press, be easy to use, ecologically friendly, and versatile in high demand production environments.
What we’re sharing comes from YEARS of hands-on experience.
If you want to REALLY know about ink, you need to talk to someone who has used it on a daily basis. Here at Colour Components, the information we are sharing with you comes from years of hands-on experience running a multiple award-winning trade printing business. In the process we have tried a lot of different inks, from many manufacturers, in all types of pad printing applications. So, when it comes to ink, you could say that we have ‘been around the block’.
Our own experience (together with feedback from our customers), has led us to use and sell only one brand, Printcolor High Performance Inks, which are made in Switzerland. As well as our own practical knowledge, as exclusive agent we have the expertise of Printcolor’s many technicians and chemists on call — so you can count on us to be here for you with the right advice and answers to any questions you may have.
Here are some of our reasons for being confident that you too will find Printcolor inks to be such good value for your business…
Real, measurable value for money.
If you’ve been pad printing for a while, you may already suspect that using a cheap ink can actually costs you more. The time you lose struggling with colour accuracy, rubbing of ink that just hasn’t stuck when it should, and messing around with different thinners and additives to get the print to transfer off the pad every time… it all eats away at your profit, and And over time, it hurts.
None of that happens with a high quality ink formulated specifically for pad printing, and that is why we recommend Printcolor.
We have clients who’s profitability increased dramatically when they made the change to Printcolor… literally, by thousands of dollars per year. The reason? With Printcolor, you eliminate problems of adhesion and poor colour coverage that leads to job rejection, you increase printroom efficiency because you’re not endlessly fiddling with the ink – you will just get more profitable work done, and you’ll use less ink and time to do it.
Higher opacity than any other ink on the market gives you solid colour accuracy.
Put simply, pad printing inks are essentially made up of pigment and binder. Pigment is expensive, and some manufactures maintain their product price point by using less of it in their formulations, leaving you, the printer, to struggle with the weak colour that is the result. You may get away with it in some screen printing applications where a thick layers of colour is printed, but never with pad printing. Pad printers lay down such a thin layer of ink that pigment content is critical for colour accuracy and coverage. We have all been there… A client wants you to print yellow on a black component, you have three options:
- Recommend they don’t do it because you know the yellow won’t cover well enough to give the bright yellow print that’s expected — which just makes you look like you haven’t the expertise to do the job.
- Do it anyway and hope the customer doesn’t reject it — which can damage your relationship.
- Waste time putting down a white first or double or triple hitting the part — which turns it into a multi-colour print job, when you can only competitively quote for a straight forward one colour print.
Ouch!
We found years ago that Printcolor ink puts an end to all that. Printcolor inks are pigment rich, giving them amazingly high opacity and excellent coverage. That means you get beautifully accurate, solid, pleasing colour, every time. And, because Printcolor use the best quality pigments, their Mixing System requires only 13 colours to mix ANY PMS, HKS or RAL shade – not the 16 plus colours you need to keep on hand when using other ink brands.
Your customers will appreciate the quality work you produce, and the price you can do it for, and that helps you ‘bullet proof’ your relationship against competitors, ensuring a more stable, secure business.
Easy to use. Easy to Change. Seriously.
Many pad printers are reluctant to change ink brands. They think it may be difficult or costly. Maybe it’s better the devil you know… It is actually the opposite. Changing to Printcolor won’t cost you money, and it’s easy – amazingly so. You’ll wonder why you didn’t change sooner!
For starters, you wont have to waste what’s left of your old ink brand. After all you’ve paid money for that! In most cases you can use up what is left of your old ink with your new Printcolor mixing system. Although, once you experience how easy Printcolor is to use, you may just end up putting that old brand in the bin anyway… we did!
We often hear back from delighted customers who have struggled with a job or application in the past, who tell us “ I mixed it up the way you said, put it in the press, and it just worked!”
Well frankly, that’s the way it OUGHT to be!
A clean bill of health (and safety!)
Australian occupational health and safety regulations for exposure to chemicals and heavy metals are often set at minimum world standards. But, as with everything else Printcolor do, they don’t aim for the minimum on health and safety.
Printcolor are deeply committed to workplace safety and the environment. Their inks are BVQI (ISO 9001) certified to be free of heavy metals, chlorinated and brominated organic compounds, organic tin, asbestos and formaldehyd. Under stringent European standards these inks are acceptable for printing toys, and many have Certificate IV clearance for use in pharmaceutical and surgical applications. Safe inks are good for the people in your printroom, they give your clients confidence in the safety of their printed products, and have less impact on our environment.
Specialist pad printing ink.
One of the many things we like about Printcolor is that they don’t try and kid you with generic formulations. Unlike budget brands, Printcolor pad printing inks are NOT screen inks that have been re-labelled. For Printcolor ‘pad printing’ ink means just that, an ink specifically formulated for pad printing applications containing richer pigments, flow agents, antistatic elements and additives to promote print transfer and adhesion.
Printcolor make a excellent range of universal pad printing inks that you will use for most of your day to day printing, and they also make highly specialised pad printing products too. These include one component inks for printing untreated polypropylene, jet drying inks for high speed closure printing, highly flexible inks for rubberised surfaces, UV inhibitors for outdoor applications, anti-abrasion paste for touch panel printing – to name but a few.
Printcolor make the RIGHT ink for the job. It shows every time you use it.
