Lithographic Printing London
The Heidelberg Speedmaster lithographic offset press, under the expert supervision of our skilled and professional team, can tackle a whole host of lithographic print you may require.
Lithographic printing is an ideal option for displaying any type of graphic and text based design to it’s best advantage, in short to medium-length runs of up to 1,000,000 impressions. The machines can print on both sides of the paper, often relying on four basic colours: cyan (blue), magenta (red), yellow and black (CMYK) but we are also able to incorporate ‘specials’ or specific coloured inks made up to be an exact match of a corporate colour or pantone® reference. The process is suitable for many applications but particularly a whole range of general commercial printing such as packaging, all types of marketing materials, books, financial and legal documents and business forms.

Lithographic Printing Process
Lithography is an offset printing process. This means that the ink isn’t applied directly to the substrate from the cylinder or printing plate. Instead, it is added to the printing plate to create the image (the artwork and text) that is to be printed. It is then offset or transferred to a rubber “blanket”. At this point, the image is transferred to the substrate – usually board or paper – to produce the finished product.
Artwork is most often created in desktop publishing packages such as Indesign and Quark or vector graphic editors such as Illustrator. It is then generally supplied digitally by exporting as PDF’s (Portable Document Format). This file format helps ‘lock down’ the design across different computing systems (iOS, Windows, Linux, etc.) helping to ensure the design looks the same off the machine as it did on the screen.
Proofing is an important process to ensure the finished product is as the customer intends – this tends to be a digital, hardcopy inkjet or wet proof. Digital proofing is where a PDF is provided after being ‘RIPed’ (digitally processed) by the Raster Image Processor (the RIP), ready for print. This allows the client to make sure that the process of preparing the print hasn’t altered the layout, images or text in any way (which can happen if links to a file or font are missing in the original files). A hard copy proof is an ink jet of the job as laid out on the printing plates; layout can be confirmed but it will also give an idea of how colours and images will look on paper. Finally, wet proofing involves taking the job all the way to the press, doing a short run and approving the actual printed output – to keep costs down, these are mostly done off press or with the client in the print room to approve.
Once RIPed artwork is approved, the job is sent to the Computer To Plate system (CTP). An image is transferred onto an aluminium printing plate for each of the colours to be used in the job (CMKY plus any specials). It is the bringing together of these images and the different colour stations of the press that go on to make up the finished image.
