Sometimes, a digital print, however beautiful, is just not enough. This is when the latest print and finishing options have their moments in the spotlight as they can add a variety of haptic and optical surface options.

Print has never been the flat, 2D experience many people think of it today – It always also meant to emboss, to punch, to varnish, giving the printing substrate very distinct surface characteristics. However, this kind of sensory luxury never came cheap, as the techniques and tools required took a lot of time and effort. Today, print buyers have three very distinct opportunities to add haptic and optical special effects to digital prints: Varnishing, structured substrates and laminates. Thanks to digital technology, added value prints also don’t have to overstretch the budget.

Varnishing inline and offline

Of course, most wide format digital prints are suitable for print varnishing in all the traditional analog ways – full varnish with a coating line or offset press, full or partial varnish in a screen printing process. There is a wide range of print varnishes available, mainly for silk screen, covering every surface option from very matte to high-gloss. Sandstone and sparkling glitter varnish or even varnishes with fragrances are widely available on the market. When UV-curing inks became a standard for digital printing, manufacturers like Fujifilm started to create inline print varnishing options with their printers.

As the additional ‘Clear Varnish’ ink was added, today full or partial varnish can easily be applied onto any digital print in a fast and painless inline process. The Clear Varnish acts basically just like a spot color, though in the digital printing process no tool or form is required for partial lacquer. It’s the UV lamp settings that determine whether the Clear Varnish inks will dry a matte or glossy surface, or just something in between. By 2008, Roland DG also introduced a textured ink option, as the Clear Vanish is printed in several layers, building up Braille letters, but also leather or wood-grain surfaces. Major print manufacturers, including Agfa, EFI and Mimaki, today offer updated inline textured ink solutions with many of their UV-curing ink printer  models.

Texture and gloss is tricky business

While texture and gloss without a doubt can add tremendous value to printing products – just think about a poster advertising an exclusive handbag, with its lush leathers ready to touch right on the printed display! – additional layer(s) of inks also add complexity to a project. It is therefore highly advisable to contact a qualified print service provider already in the early design stages. Ideally, design and varnish come together to push a common goal, making the print a sensory experience that is not so easy to forget.

As the surface is altered though, unfortunately the colors are, too – a matte varnish usually subdues the colors to a certain degree, while a high-gloss will usually highlight them, making the print appear much more brilliant. With brand colors, this may turn into a problem, more so with partial varnish. It is therefore widely recommended to ask for a proof print with the actual materials, as it is nearly impossible to simulate the effect in a soft proof. This is even more important when also adding texture, as not only the color may change from a certain angle, but also small, light letters or tiny graphic details might appear to be swallowed by many layers of ink. Not only print and finishing, but also the substrate itself has to be carefully selected when aiming for that unusual surface touch and feel.

The substrate makes the surface

It is important to remember that creating an interesting surface not always means adding an additional layer. Aslan, a manufacturer of self-adhesive films, among others, offers a Print Metal substrate range suitable for inkjet printing. The combination of printed and unprinted metallic areas allows for some beautiful effects. Lots of flexible media, as well as certain boards, for example the Katz Display Board, are available with a canvas structure. When printed onto with water-based, (eco) solvent or HP Latex inks, the surface structure will be preserved, while UV-curing inks, forming a film, will usually take away most of it.

Regardless the digital printing technology, mesh and structured media may lose most of its characteristics when treated to a thick matte over-coating, very light materials might rip apart easily with the added weight of a high-gloss varnish layer. Very absorptive boards might not dry on time, as very light heat-sensitive foils are prone to crackle under conventional UV-light (but probably are fine with modern UV LED curing). Never miss the chance to rely onto your print service provider’s experience when choosing the right substrate for your added value surface structure project!

Laminates are an alternative

Laminates are thin foils often used in the sign-making industry, for example to protect the print on a wrapped car against aggressive detergents or brush abrasion in a car wash. There are anti-slip-laminates required by law for floor graphics, and UV-laminates, matte and glossy, to extend the outdoor durability of prints. For very high-end car wraps, it became fashionable in recent years to use several layers of foil to create semi-relief structures. Many laminates are suitable for cutting plotters, thus may also be partially applied on a print for special effects like glossy, matte or mirror.

Mactac has come up with yet another option. In their Permafun range, they offer a wide variety of surface options like Peach Skin, Leather or Frost. Grafityp GL Glow In The Dark will use tiny phosphor particles for a breath-taking afterglow effect. Laminates are most often applied by calender on roll-to-roll digital prints on vinyl. It is important though to choose the right combination of printing substrate, ink and laminate for the desired application. High quality cast vinyl print media and laminates are required for 3D wraps, while for flat surfaces calendered vinyls will suffice. Technically, applying laminate to a printed vinyl film makes it a composite material with potentially different specifications and recycling quality.

Gloss and structure

Textured and glossy surfaces magically catch the attention of the human ‘touchy-feely’ animal. With digital wide format printing, designers and print buyers have a broad range of options to turn even the wildest creative idea into reality. Print service providers and sign makers can help to make even the most complex project a smooth journey. Go Wild Format!

Enjoy and Go Wild!

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.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Indian Printer and Publisher’s balanced industry journalism and help sustain us by subscribing.
