During the commercial production of flexible packaging it is important to manage customer expectations with regard to the final print quality. As with any form of professional print production, there are no absolute guarantees that your print will 100% match your original design. The following guide provides a comprehensive overview of advice and suggestions on the creation and submission of artwork to help optimize your finished product. Overall the terminology maybe quite technical, therefore, we would always urge clients to employ the services of a professional and reputable graphic designer wherever possible.
We operate a Rotogravure print process which allows customers a maximum of 9 colours, including over lacquers, coatings etc

NOTE: We will provide an electronic proof back of your artwork which is known as a die line. This will indicate all dimensions, gussets, zippers, tear notches, eurohole slots, sealing thickness and any other features that you have requested. This proof will also show the separation of colours that are needed and which a separate cylinder will have to be produced for.
Printing Tips• Print Area – We can print edge to edge, however, it is advisable to incorporate a 2mm border on the Front and Back and Left and Right gusset margins of your pouch in a consistent colour. The reason for this, is during commercial production there can be a slight drifting of the pouch film used for printing on the high speed machines which can lead to issues where design images get cut or mixed up if printing images side by side. It is also important to consider where folds occur in the packaging once products are filled inside, which can lead to some areas not being visible. For example in side gusset pouches approximately 35mm from the bottom of the pouch will form a base and will not be visible when filled, therefore it is not advisable to include text or imagery in this bottom section.
• Registration – There can be a 0.1mm to 0.2mm variance in print positioning. To avoid registration problems please ensure you do not use two or more colours to form too thin or small, text, dots, lines, dashes etc .
• Colours – Many colours that are standard for printing in this type of media may require CMYK, however, in flexible packaging , the same graphic may require more colours to be able to have achieve the desired effect. Therefore it is important to provide specific pantone colour references ( PMS number). Furthermore it is important to note that for reprints there is always the possibility that colours will not be exactly matched due the various production variances that can occur as detailed above.
• Substrates – Different material substrates can also effect the final colour presentation of a pouch. Depending upon what type of material is being used it can be noted that colours may not appear as vibrant or rich as they would on a digital printed proof. Typically in flexible packaging, the background colour will tend to be either clear or silver, which both can make the colour appear duller and also alter the actual tone of the colour. In order to compensate for this we would typically look to adjust the design through the addition of a ‘white flood coat ’ at the production stage.
• Layering – It is important to ensure artwork is submitted in layers. This is when each graphic, photo or text is defined in the artwork. This makes it much easier for the pre-press department to manipulate certain objects within the artwork , without disturbing the surrounding graphics
Informal Artwork ReviewWhen providing artwork for informal review we do not require that to be in the requested formats. Typically a high res jpeg file or pdf will suffice. This is only to get familiar with the proposed job and help the quotation process. We do not evaluate or review for artwork readiness.
Formal Artwork Submission – Production ReadyThis is when you are formally submitting your artwork as ready to go straight to production and receive a final proof in the form of a die line from swiss pac pvt ltd. for sign off. This does not include us reviewing or proofing for image or grammatical errors.
If your artwork is not in an acceptable format as requested then it will be rejected. We will note what is needed in order to get the artwork production ready. It is then upto you to make the necessary changes and re-submit the artwork. If you are still unable to comply with the necessary requirements and require some assistance then we would advise you to employ the services of our in house graphic design team.
Once the artwork is ready then a final die-line will be provided which will need to be signed by the customer before production can commence.
