UNDER THE HOOD / VERVE LED 2513 24 Issue 256 - December 2024 / January 2025 www.signlink.co.uk India would not necessarily be what you expect as the home of a leading press manufacturer, yet you would be wrong holding such an opinion. ColorJet is the country’s larger producer of digital inkjet printers which offer a wide range of products including textile, signage, eco solvent, and UV printers. The ColorJet Group was founded in 1995 and since then it has invested significantly in man hours and money to bring to market fifteen new and high technology products over eight years. Due to this innovation the company has been recognised by the Department of Science & Technology of the Indian government. From its stable of printers we take a look at the Verve LED 2513, one of the wide-format printers which ColorJet claim can print on also most any rigid substrate including wood, glass, leather, ceramics, and all types of plastic sheet or board. Colour Overload One of the USPs of the Verve LED 2513 and in fact any of the others in the range, is the combination of colours and modes that will allow for a very wide range of colour lay down. To understand the configurations, first the model breakdown needs to be understood. The Verve LED 2513R5 can have between two and nine printheads which can deposit ink at seven picolitres. The second in the range is the Verve LED 2513R6, which can have three to nine printheads, this time with a capacity of five picolitres. The detail in the combination of heads is the choice between either the GEN5 or GEN6 printheads which will obviously give you differences in speed of production and or resolution — this giving the R5 or R6 suffix to the model numbers. The speeds can also vary depending on how many heads are deployed of each version, but in bare facts, the speed ranges from 12m2/hr up to 68m2/hr when you have select GEN6 heads in three rows. Depending on mode and head/row selection, the DPI varies between 635 x 600 up to 635 x 1200. The Ricoh printheads have for a long time been the industry benchmark for quality printing and it makes an obvious choice for ColorJet. The main difference between each head being the volume of ink that can be deployed at the same DPI with the GEN6 version having more capacity then GEN5. As for colour, the Verve LED 2513 can print in the standard process set of CMYK along with a white and varnish. There can be issues with white inks, as the industry and users know the pigmentations within white ink can suffer from settlement. All the inks and coating are cured with the use of a LED drying system, meaning the product is dry on production. If this is not attended to, the pigments can block tubing and ink jet heads causing both damage and poor print reproducibility. ColorJet have designed into the Verve LED 2513 a white ink circulation system which moves the ink within the system which stabilises the ink and avoids the pitfalls of white ink. A further design feature of the Verve LED 2513 is what ColorJet call the Dual Negative Pressure System for separate white and colour ink supply. The system has a display which shows the pressure in the supply for greater print control and productivity. Finally, do not be concerned that you Colour Combinations India’s biggest manufacturer of digital printers, ColorJet, has a number of flatbed printers to match any appetite for solid substrates, the Verve LED 2513 is one of those choices The ColorJet Verve LED 2513 comes with a choice of GEN5 or GEN6 printheads
