Inkjet Poster Printing
Inkjet printing uses the same technology as your home printer. Inks contain a pigment that is dissolved in water and is applied to the poster using a print head. Advantages of using inkjet include high quality colour reproduction. Inkjet's disadvantages are that colours will run if the print gets wet and prints will fade over time. Fading accelerates if the poster is exposed to direct sunlight. Clockwork uses special UV stabilised inks for its inkjet prints which prolong the life of posters and an 8 colour printing process that gives the best large format colour reproduction possible. Clockwork can print up to 1.5 metres in width by any desired length
Solvent Poster Printing
Latex printing is the newest and most flexible technology to hit the market. It uses water based paints to print an image on either paper, vinyl or other synthetic substrates. The ink technology is based on the same formula as paint you would buy from a hardware store. The ink is applied by a print head, then passes through a special drying area in the printer where the water is evaporated, leaving the paint like particles behind with the ink sitting on top of the material. Like paint, it’s very durable, UV stable and suitable for outdoor use but latex prints are not as hard wearing as a solvent print counterpart. The water based nature of the ink makes it suited to printing Point Of Sale (POS) posters and fabric posters.
Monochrome Poster Printing
Clockwork operates 5 large format laser printers that can produce hundreds of monochrome posters per minute. These printers put down toner which is fused to bond paper using heat. Large format plan printers produce prints up to 900mm wide and any length. Rolls of paper come in specific width to provide ISO sized plans in A3, A2, A1, B1 and A0 sizes. Colour laser wide format plan printers do exist, but to date their complexity means that reliable performance can be difficult to achieve.
Offset Poster Printing
The offset printing process uses special embossed flexible metal plates to create an image on a set of rubber rollers covered in ink. The metal plate and rubber roller are in contact with each other. Where the plate touches the roller the ink is squeezed off. The rubber roller then is pressed onto the print media, hence the term offset print. Offset produces high quality and consistent image quality, but has higher setup costs. For posters, offset usually becomes cheaper at around 100 copies. Offset is usually limited to sizes of about A1 (841x594mm). For large poster quantities, offset printing is the method of choice.
