Using the best in print machinery with personal close attention to detail, we pride ourselves on the ability to produce quality results and always continuing to do so.
Offset printing is the best choice when considering your next project where very high quality and medium to high volume copies are required.
Offset printing also provides extremely accurate colour with sharp and clean image reproduction.
The Offset Process:
- Offset is one of the most common ways of creating printed materials.
- The technology uses aluminium plates to transfer an image onto a rubber ‘blanket’ and then rolling that blanket image onto the sheet of paper.
- Offset printing uses CMYK and Pantone Matching System (PMS).
CMYK process inks is the commonly used print process
When preparing an image for printing in CMYK, the electronic file is separated into the four primary colours Cyan, Magenta, Yellow and Black.
The image is recreated using screen tints made up of small dots that are applied at different angles to the four process colours. The four processes are then printed one after the other to recreate the original image. The CMYK colours are manufactured colours and are not mixed.
The Pantone Matching System (or PMS for short) uses a pre-mixed colour formula to create a large number of ink colours. It is a standardized colour reproduction system. The pantone colour chart contains colour swatches created from a palette of basic colours. Each colour is identified by PMS number assigned to it. These numbers are used to identify the exact colour required. The specified ink is then prepared using the correct mixture of base colours, either purchased pre-mixed from an ink supplier or mixed by our operators. PMS is also commonly referred to as Spot Colour.
With our constant focus on the environment, all Lionheart inks are vegetable based.
Soy and vegetable products are used in ink for their oils, which act as the vehicle for the ink pigments. This Ink is made from a variety of vegetable oils such as corn, walnut, coconut, linseed, canola and soy bean. Vegetable based inks release only about 2-4% VOCs into the atmosphere………And the best thing is they are a renewable resource!
Lionheart Offset printers have several Heidelberg Offset Printing machines- SM -52 for smaller jobs and the CD 74 (pictured) for larger runs
An ISO proof (or Hardcopy proof) is a printed simulation of what your final output on a printing press will look like.
An ISO is produced on an output device that’s less expensive than a printing press.
ISO Proofing is created by printing a PDF file (supplied Print Ready Art) on standard proofing paper.
ISO proofs are produced prior to plate making and are used as a close print reproduction of the file supplied.
Proofs are than required to be inspected very closely to make sure everything is correct. Once satisfied that everything is fine and approved then it will go to print.
Alternatives to ISO Proofs are PDF Proofs, which after inspection of the initial file supplied, is checked and then emailed as locked file. PDF’s are often used when tight turnaround productions are required – or colour components are acceptable to online visualisation.
Benefits for ISO (Hard Copy) Proofing
Errors with a supplied file sometimes cannot be seen when doing a PDF Proof.
- Imposition: Text and Image components placed outside trim areas
- Pagination: Multi-page documents (i.e Books) Use mock ups to help to be certain that all content is in correct order.
- Missing art or elements due to transparency issues: Sometime due to transparencies, the PDF proof (or Soft Copy) will not pick up these errors. It may look ok on the screen, but when printed the background transparency will be converted into something unpredictable. There are many reason it happens, Hence it is very important to flatten to PDF before sending files.
- Spelling & Grammatical Mistakes: Hardcopy is also a much easier way to catch spelling and other mistakes when read on paper then viewed on screen.
- Low Resolution images: Images can look great on screen, but when printed look pixilated, due to the fact a screen is 72 dpi verse print which is 300 dpi.
Note: Hard Copy Proofing is not meant for colour approval. We print to industry standard colour and the hard copy proof which is sent was printed on standard proofing paper on digital press method. If a job is colour critical and needs a high level of colour accuracy then a press check is usually advised.
