Switch to carbon infra-red emitters halves drying times says Calmatech
B
y replacing halogen emitters with Heraeus carbon infra-red emitters, Calmatech has been able to halve the time required to dry screen printing on T shirts. The new heaters have also proved more energy-efficient and have improved the quality of the finished product. The medium wavelength of the carbon infra-red emitters is optimally suited for surface drying, as this wavelength closely matches the absorption characteristics of water. By contrast, the short wavelength of halogen lamps is more penetrative so that energy is lost as it penetrates the ink and the textile itself.
Since the replacement, the new emitters, which are fitted precisely in the dryers to create an even heat distribution over the target textile surface and are easily programmable by an operator or by automatic control, have demonstrated significant energy savings. This is
because of the better water-removal capability of medium wave radiation and also because carbon emitters have a very short response time. Consequently, they are suitable for pulsing and are switched on only when required, in contrast to the halogen emitters, which needed to be switched on permanently.
Jurgen van Oostrum, managing director at Calmatech, said: "The switch to carbon emitters has made our flash cure much more efficient. Formerly, it took seven to eight seconds to dry screen inks with the halogen system. With the carbon emitters it now takes just two to three seconds. This is of great benefit to our customers, who are very appreciative of the energy savings resulting from the reduced drying times. They are also very pleased with the fact that the less-penetrative medium wave dries the textile surface more gently, without discolouration and without heating the print pallet."
Introducing the Ricoh Ri 1000 T
he newest DTG printer from Ricoh, the Ri 1000, offers high-performance features at an affordable price for users ready to launch or grow their garment printing business. It delivers incredible flexibility and image quality in an
affordable, easy-to-use package, perfect for both new and experienced users.
The Ricoh Ri 1000 was designed with walk-up ready ease of use in mind. Automated maintenance sequences clean print heads and agitate white ink regularly, saving operators time and making the device easier to use and maintain. The Ricoh Ri 1000 continuously monitors its ink supply, air level and dampers, adjusting where necessary so it is virtually always ready to print.
For those maintenance tasks that aren't automated, the device's 7in touch screen display includes a built-in Interactive Operation Guide, which provides alerts reminding users to perform manual maintenance tasks. This touch screen also allows for intuitive job and workflow management.

Summa launches 3.2m flatbeds for the textile market
S
umma has introduced two new sizes of its finishing flatbed systems – the F3232 and F3220. These systems are based on the proven technology of the Summa F Series and are expected to be released by April.
Both the F3232 and F3220 cover a working area of 3.2m, making them the ideal companion to process common, popular print sizes with ease and accuracy. Geert Pierloot, Summaʼs product marketing manager, said: “The new sizes of flatbed systems enrich Summaʼs platform with advanced finishing solutions, especially with the textile industry. Together with the recent launch of a more powerful High Torque Rotary Module (HT RM), both the F3232 and F3220 are the ideal workhorses to serve the textile market in the processing of all sorts of mesh fabrics, flags and banners.”
All existing tools and models within the F The Ricoh Ri 1000
Series gamut are designed to fit each size of the flatbed range, the F3232 and F3220 sizes inclusive. This ensures versatility to process all kinds of material and offer numerous high-end solutions to the sign making, textile and digital print industries.
