About

ArtStack's Prints are created using the most advanced LED photographic printing technology.

They offer the truest reproductions of incredible artworks from the world's leading museums, scaled according to the originals' dimensions - a unique opportunity to own great artworks in the manner they were intended to be enjoyed.

We use the specialist LumeJet S200 printer to combine – for the first time, and on the same page – true contone photographic image quality with crisp fine lines. Featuring unique, patented photonic technology, the LumeJet S200 prints ultra high resolution 400 dpi contone, considered to be better than 4000 dpi halftone quality for achieving images that truly show no digital patterning at all. 

The LumeJet process is considered by commentators to be the only real production scale digital print technology that actually exceeds the quality of offset lithography. 

Our ultra high resolution prints mean you can really appreciate all the brushstrokes and textures of the original artwork. For colour fidelity, we are second to none, matching a vast range of colours, including metallics and neons, on media that is colour-fast and light stable for many, many years without additional protective coatings. The prints have a higher resolution and sharpness than conventional silver halide (C-Type) processes, excellent colour fidelity and high dynamic range. 


Key advantages of this process include:

1. Ultra High Quality Printing – considered to be better than 4000 dpi inkjet quality

2. Fine Graphics and Contone – pin-sharp prints without dot gain for true photographic quality images

3. Original Proportions – we are unique in custom printing based on the original proportions of the artwork, rather than printing to standard sizes for an off-the-shelf experience - so you get the full image without cropping

4. RGB Colourspace – more colours than CMYK, matches hard-to-print Pantone® spot colours, ICC profiles

5. Inkless Printing – process uses fewer consumables, and involves no wetting or offset

6. Edge-to-Edge Printing – no bleed, no trim means less waste and less maintenance

7. Great British Technology – developed, marketed and supported by LumeJet in Coventry



How our contone prints differ from traditional halftone prints

For high end colour printing applications, there’s a traditional divide between contone and halftone output. Contone prints on photographic paper are widely regarded as the benchmark for image quality, longevity, colour fidelity and competitive cost; whilst halftone methods have become something of the default for text, line art and convenience.

Continuous tone photographic images contain an infinite range of colours, and no dot structure. They’re produced via a wet chemical process that uses the reaction of light on substances in photo-sensitive paper to achieve incredibly smooth images. This is wonderful for pictorial graphics and photographs, but less successful for text, which becomes blurry and illegible at small point sizes.

Halftoning was developed in the nineteenth century as a way to reproduce photographs in newspapers, it reduces shades to patterns of dots of different sizes, shapes or spacing which could be printed with a single ink. At that time, the majority of printing was for words on paper – black text on a (white) background. Halftones simulate continuous tone images by optical illusion: the human eye blends the dots into smooth tones.

For a single colour ink (black and white images), halftoning is relatively straightforward. Colour printing with multiple screens is more complicated, as it’s important to keep the different coloured dots close together to fool the eye into seeing different colours. However, overlaying dots of different arrangements may cause unwanted visual effects like moire patterns. Positioning the colours at different angles reduces this problem, and groups the dots into characteristic rosettes.

The unique production process we use features new, photonic technology to print digitally on standard photographic roll paper, achieving ultra high resolutions and pinpoint accuracy with all the benefits of photo paper – true contone images, giving you a far superior product.
