How To Prepare Your Artwork?

Step 1: Choose The Mode Of Packaging

Different sizes and origins for a specific form or design of a product should be created for flexible packaging, for example:

  • Does the pack consist of a bag, sachet, wrapper, or a pouch?
  • What are its actual measurements and level of acceptance?
  • Are there any unique specifications or characteristics such as tear clicks, hanging holes or openings, gussets, shutters, zippers, or spouts which need to be implemented/incorporated?
  • Are there any form of criteria and test procedures which need to be followed?
  • Which substrates and printing methodology is being utilized?
  • How are the packages secured? Would heat affect the inks used if it is applied?

These elements must be integrated into the customer criteria and job parameters, which tend to shape the submission of the request and the procedure for the task. Both the pre-press stage and the first phase of design and production, followed by processing, printing, and conversion as needed, maybe automated depending on the function of both the printer and the converter.

Since a section consisting of a date, batch or barcode is also needed, it is vital to include bag drawings from the system manufacture when printing the packaging film that will accurately show where printing is feasible or where is not possible, they consist of:

  • Developing both the actual size and shape appearance
  • On-screen layout and configuration
  • Placement of text, barcodes, and graphs on the appropriate positions
  • Actual trimming of sizes
  • Accurate placement of register marks
  • Slitting; step-by-step repetition

Step 2: Artwork Creation

Different brands have their distinctive style. For instance, a brand may be fascinated with a specific background color, a precise symbolic picture, a particular shape, and some visitors may stress, in particular, the original meaning of the brand’s logo. Therefore, in order to illustrate the most relevant details on the packaging, we need to comprehend the actual design sequence.

Studio Designer contains a 3D demonstration kit which when provided with all graphics text and artwork assists by providing a moving 3D image of the finished product which turns around and can be viewed from different perspectives as if being handheld. By giving the artwork any modification, it will instantly be viewed on the 3D pack.

The Studio Designer can immediately see if gussets or seals will hinder the design elements. Nonetheless, it is possible to identify the opaque white backing, sealing reliefs and metallic ink, if the designs are opened in Studio Visualizer. The visualizer can also portray well the backside appearance of the package. So, the product owners will be able to see first-hand how the item will appear, with regard to both retail and in comparison to the market.

Virtual real-time images can also present, in the proper sequence, the various printing and finishing processes, and on the right substrate – whether gloss, clear or white plastic films, matte or coated paper, spot colors, and Pantone colors, reversed printing, and many others.

The actual physical measurements, top, bottom, and back-sealing areas, and the available regions for pack graphics can all be seen and altered per the requirements. In order to meet the right conditions, the development process must provide the front of the packing and the two regions on both sides of the central part of the vertical back seal for graphic design images, brand identity, bar codes, etc.

The gussets would be placed inwards during pouch manufacturing operation on the shape, filling and sealing system, forming the gusseted framework, filling the packet, and then sealed at the top-end. For the Pillow Pouch, the backpack’s central or off-middle area will be sealed, allowing one entire face and two half faces to fulfill the text and graphic specifications. On pillow and gusseted packs, the back enclosing can be overlapped (a Fin Seal) or pasted (a Lap seal) in one of two, left-over- right or right-over-left. Such forms of seals would be further clarified and then demonstrated. The graphic will then automatically change based on how the seal is picked.

Looking now at the actual layout and creation of the flexible bag, which consists of the top, right, left, and bottom seals, which are optional and gusset in the bottom, or a Stand-up Pouch, it is notable that the structural design is again very different. Based on the components used, various forms of stand-up capabilities may be accomplished. Construction of both paper and plastic provides different choices.

For the stand-up pouch development, the streamlined form requires a natural dual fold so that the bag will stand straight and expose the side seams. A broader top-sealing region is also available. The stand-up pouch also has a wide graphical area with a broad double front and back. In order to follow different design specifications and shape, filling and sealing machine requirements, both physical measurements and sealing areas should once again be defined.

A precise instance of a pack structure exciting both narrow and mid-web converters due to its simplicity and comparatively small nature (many of which can be stepped and replicated over the width of a narrow-web press) is that of the three-side or four-side seal sachet. The front and the back of this form of a sealed sachet are presented for graphics. These may be screened on all four sides or three sides, folded down on the lower side, and then fixed on the left, right, and top.

Step 3: Color Management Consideration

While the Roto-Gravure & Flexographic method used by most lightweight packaging works and can derive the desired output, that only becomes feasible if the manufacturer takes the limitation of these approaches into account. Usually, designs are produced in conjunction with CMYK procedure and spot colors. Often tiny parts of the CMYK printed text and edges may be partially separated from the print kit through minor dot-registration changes as the web passes through the press. However, instead of CMYK, the usage of spot colors will yield improved outcomes if comprehensive parts of the artwork are to be robust in color.

color management

For a clear image to be distributed, a solid white pigment needs to be backed up to differentiate the following colors. It is usually difficult to read the printed document explicitly on a clear image; without white, the printed product tends not to look good. If a transparent window area is not required, an ink cost-saver may be used with a white sealing Site, including White PE and CPP.

Therefore, efficient, versatile label printing can be crucial for brand color control through diverse substrates. The desired color of a brand will certainly differ depending on the specific substratum that is being implemented, whether it is a paper or transparent, metallic, or white films. Initial fingerprinting would be required for materials so that the origination process can start. During the production and construction phases, color pallets need to be handled carefully, while color retouching is also required since it is usually crucial for better performance.

If flexible packaging artwork needs vignettes or gradient sheets, it should be noted that Roto-Gravure & Flexo-printing machines cannot print less than 10% of the correspondent matrix. When switching from a first screen to a zero percent screen, a hard-line edge-best is typically prevented in the artwork design. There is often a propensity to obtain dots on fine displays for specific substrates.

Step 4: Consideration

Barcode orientation

The barcode must be positioned in a simple, reliable, regular position on the rear or (inward) the package’s base for easy scanning of retail packs. The icon must be displayed with a sufficiently visible light margin. The device must be defined as a bar code on a smooth or continuously bent surface with a standard 8 mm to 5 mm minimum from some package seams or foils.

For some narrow curved pouch surfaces, the bar code may be printed vertically to the curvature, based on the scale and width, to eliminate future complications and obtain improved performance.

Seams

It is essential to consider that the longitudinal seam may be shaped in one way or another, which may influence the seam’s depth and dimensions of the press thickness. In a straightforward overlap seam, one edge is placed over the other corner (Lap Seal), and the two sides are sealed together. Although, this sort of seam is only feasible if the insides, as well as the outside of the substrate, can be sealed or if the substrate is lined with scrubber cover on the exterior, typically with polyethylene ( PE) or polypropylene (PS). Due to the fact that overlap seals need less content than elegant seals, packagers turn them into lap seals for durability, lean operation, and economy.

It is of utmost importance to note that when the packs contain a crossed surface, it cannot be pre-treated for printing on the outside of the cross surface because this renders it difficult to get a secure seal.

The longitudinal seam may preferably consist of an edge package folding over and then sealed on the inside of the other regional edge, depending on the packaging material and the form of the box. This sealing method is also known as the fin seal. It should be noted that the fin seal technique tends to require a more considerable pack overlap. Generally, the longitudinal seam overlaps are usually 15mm to 25mm based on the seaming process.

Registration marks

A registration label must be printed on the site for both correct Internet printing and examination, and the following form, fill and seal system operations. The Web transport will be directed with one register mark for each product number, which means that one bag is transported through formwork, loading, sealing and product cutting machine loop on a variation of the registered mark on the printed platform, as well as a picture cell on a forming and loading system.

Tension and edge control

It is stated that both pressure relief and rewind be servo-controlled in order to ensure a stable web tension, especially for certain thinner gauge plastic films for flexible packaging. In the case of high or low pressure, it may cause unregulated spreading of the image, generate inconsistencies in product duration and misaligned printing, out-the-round rolls, registration changes, blocking, collapsing of cores, telescopic lines, bagging or corrugation – critical factors which are quite relevant in managing the customer’s form, filling and sealing machinery.

Wounded rolls may even create a blockage and bind onto the network layers. Such rolls are often extremely residual or strongly in-wound tension, which allows the film content to expand or distort as tension is released while the rolls are curatively processed.

Various flexible packaging films, which occur during the coating or lamination phase, or the extrusion method, may have differences in machine thickness which exaggerate when the bucket is wrapped and produce high spots and cords.

A completed roll in-wound tension is consequently an essential element determining if the flexible packaging roll is of decent or bad quality and if it will perform well at the stage of bag, pouch or sachet forming. Ideally, rolls may be wrapped more firmly in the middle, and then woven less securely, as the roll slowly grows in diameter.

Multi-layer film laminations also have barrier layers of foil using network tensions close to those on papers and comparable to the pressure-sensitive content tensions recognized from mark converters. Nevertheless, thin films, which include only one or two film laminates, need a specially built press to process the delicate materials.

In most cases, this would consist of:

  • Increased control in tension level that is needed for pressure-sensitive presses
  • Lower tension servo-driven unwind and rewind
  • Using a web route optimized for extensible components, including idler rollers and low friction, smooth turning bearings
  • Handling of optimum roll
  • Introduction of a cold/cooling UV light system
  • Integrating a chill roll or chill drum for web temperature regulation.
