On 13 January 2022, HP Large Format Printing held a virtual but live demonstration of its Latex 700 and 800 series inkjet wide format printers. The demonstrators showed how these printers could meet the market demands with their high media versatility, productivity, and sustainable technology. The idea was to show how these latex series could boost business and be more profitable for the print service providers.

In a live demonstration, HP expert Jeremy Brew Large Format Solutions & PrintOS expert, HP Worldwide discussed the details about the HP latex 700 W printer and how its water-based inks gives the best color consistency, is easy to handle, and is environment-friendly. Then, Kevin Gregory, application specialist at HP Large Format Printing, showed the white ink system option and how it works on the Latex 800W. They talked about the safety and health aspect for the operators also.

The HP latex 700W and 800W provide vibrant color output at high speed and further improve printing productivity by using polypropylene or synthetic papers of substance weights as low as 110 gsm. The technology is designed for sustainable impact through the entire system and workflow of the printer, cartridge materials, ink chemistry, printer operation and production, the print itself, its display, and the end-of-life disposal of the product.

The operations of these printers can be controlled virtually anytime and anywhere with HP’s PrintOS tools. The latest water-based inks offer a more comfortable and welcoming operation to sustainability goals and differentiate printing businesses. No manual maintenance is required on each head of the printer, no wiping or excess jetting is needed to keep them running.

HP white ink workflow

This was the first time that HP showed its white ink for 64-inch wide printers, and in the webinar, Gregory described the different methods for adding white to prints or once can say about the white printing workflow. There are four categories for this workflow which include the underflooded mode and full-page coverage, overflooded mode and full-page coverage, sandwich mode and full-page coverage, and spot mode.

  • Underflooded mode and full-page coverage – In this, the white ink is printed on the substrate, enabling it to print color on a wide range of substrates. It can be used in printing on non-white or transparent substrates.
  • Overflooded mode and full-page coverage – Here a white layer is printed on top of the color layer allowing the creation of new colors by playing with white ink translucency. For instance, it is used for printing on a transparent substrate for window decoration.
  • Sandwich mode and full-page coverage – In the sandwich mode, a white layer is embedded between two different images, allowing a different image to be seen on each side of the substrates. An application example is flipping signs.
  • Spot mode – For spot printing in some cases, white ink is printed in a particular area in the same way as any other color. Also, spot color information is required in the file. It is used to print on transparent substrates while keeping some areas transparent.

Gregory also demonstrated several large-format print applications that can help print and signage businesses grow both volume and value. The webinar ended with more discussion on sustainability and decreasing operational costs by using the HP latex 700W and 800W.

 

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.
