HD printing uses special colours – not CMYK. A CMYK image will be separated into special colours during reproduction. Because the screen ruling for HD printing is higher a representation of an image will be closer to the original, but still will not match it exactly.

Avoid using colours which are needed in an image (a), elsewhere on the can (b). This will allow Ball to best control these colours used in the image in production.

Fading to 0 under circumstances is possible, although leaving an even soft edge over a big area of the can does not belong to the possibilities (dots will not consistently hold on the plate).

It is possible to create an optical illusion of a third colour by partly overlapping screens. This will only be applied to screens and in order to get the best possible end result, it will have to be done by a Ball qualified specialised reproduction studio.

Can printing uses spot colours – not CMYK. An image using CMYK colours is separated into spot colours during reproduction. The aim is to give a close representation of the original, but it will never match it exactly.

A screen should continue over the entire surface of the can, fading a colour to zero and leaving a soft edge is not possible due to the dot gain experienced in the can printing process.

Avoid printing colours wet-on-wet as much as possible. Due to the nature of the printing process we have limited control over the final result. Colour variation in batches can be expected. Wet-on-wet printing can only be considered with complimentary colours, screen size & angels. Contact Ball in a very early stage of the development process, so we can help you achieve the best result.

It is not possible to create a third colour using two colours printed on top of eachother. The consistency of this colour cannot be guaranteeed throughout the production. It results in contamination of the colours in other areas of the design.

The process used to print cans is called “Dry-offset letterpress”. This means that a printing plate is used for each colour to print that part of the image to a blanket. One common blanket collects all the different colours, until the full mirror image of the design is complete (1 rotation of the blanket). The blanket transfers all the colours at once to the can – see also print processes for more details. Maximum resolution used in can printing is 120 LPI. During the reproduction process the customer supplied artwork is separated into spot colours and the relevant screen ruling applied. We also introduce “air gaps” to protect the design against colour contamination during printing. This process can only be carried out by a Ball qualified reproduction studio.

Vignettes should always run from top to bottom (vertical) with a maximum of two colours opposing.

Horizontal vignettes running around the can should be avoided. Due to the nature of the process small differences in pressure at print stage and the lack of controls of ink in the print direction make it impossible to control the printed end result.

Because a can is cylindrical, your design will overlap on itself by approximately 2 mm. Point-to-point contact in the overlap differs by production line & size. Perfect alignment can therefore not be guaranteed in the overlap.
We recommend to keep the overlap free of any continous graphics and text. An ideal overlap has the same solid colour on either side of the design.

AirGaps

Artwork with air gaps

Printed result on can

To protect the colours on your design from contaminating, Rexam adds small gaps between all design elements in different colours during the reproduction process. The size of the gap depends on the colour and the size of the elements in this colour. Air gaps disappear as they typically fill up with ink as this spreads during production. They are calculated to suit each of our plants to protect the colours on your design from mixing.
As these gaps are specific to our process they can only be added by a Rexam qualified reproduction studio.

In the spotlight: High Definition – Printing

Ball’s High Definition special finish is a combination of printing plates and premium design separation. This is allowing us to increase on the resolution which we can achieve in can print. Due to the nature of the printing plates, the dot gain visible on the final printed can is less than normal. Premium design separation helps to create the optical illusion of overprinting.

Invite us to your creative dialogue and we are happy to advise you at a very early stage in the creation of your High Definition design.
