Q1. We are not based in the UK so can you supply export markets?
A1. Over 90% of Natgraph’s output is exported with Europe, Asia and North America being key destinations.
Q2. We are not in the printing industry but think Natgraph may be able to build equipment to our specific needs…………can you help?
A2. Yes, we have built numerous special purpose machines for print and non-print applications. Please get in touch.
Q3. We would like to have our new equipment painted in specific colours. Is this something you can do?
A3. Yes, like all aspects of our equipment we are happy to offer specific design features, and this can include paint colour.
Q4. Do you have local representatives in our country?
A4. We are pleased have an extensive network of distribution partners around the world who have the experience and knowledge to support you all the way through to installation.
Q5. I see that you are focused on screen printing but I need a solution for offset and digital printing. Can you help?
A5. Yes, we are very experienced with these applications and have solutions developed to match these processes so please get in touch.
Q6. What substrates are you accustomed to working with?
A6. We support applications concerning a wide range of plastic materials, paer, wood, steel, aluminium and other engineered materials.
Q7. Do you build gas dryers?
A7. No our equipment is based around electricity. Our opinion is that this is cleaner, more uniform and more controllable than gas and this is critical to our customer’s quality needs.
Q8. What PLC brand do you use to control your equipment?
A8. Our house default is Siemens but we have worked extensively with Mitsubishi and Allen Bradley
Q9. How long are your dryers?
A9. The length of the dryer is dependent on the application and is influenced by the chemistry of the ink/coatings and also the process speed. We have built dryers from 2.5m through to 36m.
Q10. Do you offer LED for UV drying?
A10. Yes, we have high performance and competitive solutions for that. Screen print has been slow to adopt this technology largely because it is typically a low volume, high mix process. Availability of ink, equipment price and limited wavelengths have inhibited adoption. We expect that to change in the coming years so, as you would expect from the World Leader, we have solutions that are compatible with our equipment. Please get in touch to discuss.
Q11. What are the variables that affect solvent drying?
A11. Time at temperature is fundamental but other variables include air speed and IR intensity. Our experience and focus on precision and control of all variables mean that we understand drying like few others. Get in touch and we can help you to define, optimise and specify your drying.
Q12. Is LED more efficient than conventional doped lamps?
A12. Not necessarily. Our Intelligent Energy Control Feature bridges the energy gap by around 50%. If you then consider that most modern LED solutions require water cooling and this requires a refrigeration plant that consumes energy then the difference is very small. Indeed the difference at this time does not justify the high cost of LED kit but this will almost certainly change over time.
