What Is Laser Printing?

Lambda and Lightjet are both brands of laser printer companies (Durst and Océ, respectively) that developed innovative digital replacements for traditional darkroom printing. Rather than using a bulb to expose light on photographic paper, these printers use three lasers (red, green and blue) to expose light onto photographic silver halide paper, advancing through the Lambda and in the Lightjet, rolled inside a large drum. The exposed paper is then processed in photographic chemistry to create a perfectly archival, digital but traditional C Type print. Hence the term, “Digital C Type“.

The Durst Lambda was one of the first ever laser printers to produce C Type photographic prints. The technology uses a continuous roll-to-roll single beam, 3-laser (RGB) exposure system which means that you can make prints up to any length, with a width of up to 50”. How does it work? Digital information is exposed directly onto conventional photographic media. Linear writing speed is superfast with a choice of 200 and 400 ppi (equal to an apparent resolution of 4000 dpi)resolution. The Lambda produces images with the highest possible resolution (68 billion colours!!!)

Laser systems rely on elaborate combinations of rotating mirrors and lenses that must remain in alignment through use. ‘Uniform spot size and shape’ means that even the edges and corners of a Lightjet print are as razor sharp as the centre. This uniformity is better than any other optical printing technique. This technology results in better image sharpness, uniform density and colour and the highest geometric accuracy over the whole print.

But at Metro Imaging we know that the needs of photographers, are quite specific and based more around the quality of the image, rather than the speed or efficiency of the machine. For artists and photographers the key issue is resolution and image quality. Here laser printers win hands down.

Compare, for example the Durst Lambda (laser) printer with two commonly used LED printers: the Durst (LED) Theta printer and ZBE’s Chromira:

Printer	PPI	DPI equivalent
Durst Theta LED	254ppi	1,200 dpi
ZBE Chromira	300ppi	1500 dpi
Durst Lambda Laser	400ppi	4000dpi
Océ Lightjet Laser	300ppi	4000dpi

C Type Professional Photo Printing

We have been printing the highest quality C-Type prints for decades and digital C-Types produced on our Lambda have the archival and tonal benefits of traditional photographic papers, with the advantages of digital photo printing. C-Types are a conventional photographic print from a digital file, and as such is the most suitable option when printing a colour photograph.

Fine Art Giclée Printing

We have Hahnemuhle and Canson Giclée Certified Studio staus and with over 30 years experience in photographic printing we use the most advanced inkjet technologies. Giclée is a gallery-quality inkjet print onto fine art watercolour paper. This is most suitable for art illustrations, but can also be used for colour and B&W photographs.

Black & White Printing

We have worked in collaboration with Harman Technology to develop genuine B&W silver gelatin Fibre-Based and Resin-Coated photographic prints from digital files. The Resin-Coated is suitable for most types of B&W printing, and Fibre-Based is ideal for exhibition quality.

Duratran Printing

We produce Duratrans at a quality level unmatched by anything else out there. Duratrans have to be lit from behind, so need to be mounted in a rear lit display, or we can produce led lightboxes, which are conventional photo frames containing the Duratran and led panel.

Metro called it Direct to Media. Essentially this is a UV printing machine that can produce very large, up to 3m x 2m prints on any flat material less than 10cm thick. So we can print on wood, metal, slate and pretty much anything you can think of.

Direct to Media Printing

Direct to media printing is exactly that; we print your image directly to a substrate of your choice. Be it paper, card, aluminium, Perspex, canvas, wood, slate… Our Jetrix UV inkjet flatbed printer can print on any flat surface up to 3m x 2m, less than 10cm thick. To ensure your material is suitable, we can print test prints around A4 in size.

This is a print on adhesive vinyl. The vinyl is on a roll and 1.2m wide, but it can printed in multiple pieces in order to cover a wall.

Vinyl Printing

Vinyl Phototex is chosen for its high-quality Giclée finish as well as its ease of application to wall or mounting material due to its self-adhesive properties. We can print on vinyl using our direct to media printer, in strips of 1.5m x 3m and these can be applied to the wall in the fashion of wallpaper to cover a complete wall or interior.
