What is the difference between Laser & LED 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‘.

Laser printers such as Lambda and Lightjet are the preferred choice by artists and photographers the world over. Laser systems rely on elaborate combinations of rotating mirrors and lenses that must remain in alignment through use. LED technology uses a Light Emitting Diode print-head as a light source which is ‘solid-state’ (i.e. fixed) and has no moving parts.

But at Metro Imaging we know that the needs of photographers, particularly for fine art, 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 a commonly used LED printer: the ZBE’s Chromira:

Printer	PPI	DPI equivalent
ZBE Chromira	300ppi	1500 dpi
Durst Lambda Laser	400ppi	4000dpi
Océ Lightjet Laser	300ppi	4000dpi

We offer the following types of printing

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.

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.
