What You Need to Know About Esko Bitmap Viewer 10 and Screened Files




Esko Bitmap Viewer 10: A Powerful Quality Control Tool for Screened Files




If you are involved in the printing industry or any other industry that requires high-quality screened files for output generation, you know how important it is to verify the content and printability of your files before you make plates from them. Screened files are files that have been processed by a raster image processor (RIP) to convert continuous-tone images into halftone images that can be printed by a printing device. The quality of screened files depends on many factors, such as the type of screening method used (e.g., amplitude modulated or frequency modulated), the ruling (the number of dots per inch), the angle (the orientation of dots), the dot shape (e.g., round or elliptical), the dot gain (the increase in dot size due to ink spread), the resolution (the number of pixels per inch), the minimum dot size (the smallest printable dot), etc.

What are Screened Files?




Types of Screening




Screened files are files that have been processed by a raster image processor (RIP) to convert continuous-tone images into halftone images that can be printed by a printing device. Continuous-tone images are images that have smooth gradations of colors or shades, such as photographs or paintings. Halftone images are images that have discrete dots of varying sizes or shapes that create the illusion of continuous tones when viewed from a distance, such as newspaper or magazine images.


Screening is the process of creating halftone images from continuous-tone images by using mathematical algorithms that determine the size, shape, position, and orientation of the dots based on the tonal values of the original image. Screening can be done in different ways depending on the type of screening method used (e.g., amplitude modulated or frequency modulated), the substrate (the material that is printed on), the printing device (e.g., inkjet or laser), etc. There are three common types of screening methods for printing: - Amplitude modulated (AM) screening: This is the traditional method of screening, where the dots are arranged in a regular grid pattern and vary in size according to the tonal value of the image. The smaller the dot, the lighter the tone, and vice versa. AM screening is also known as halftone screening or conventional screening. AM screening is suitable for printing on smooth and uniform substrates, such as paper or film, and for reproducing text and graphics with sharp edges and fine details. However, AM screening can also cause some drawbacks, such as moiré patterns (interference patterns caused by overlapping dot grids), rosettes (circular patterns formed by dots of different colors), and dot gain (the increase in dot size due to ink spread). - Frequency modulated (FM) screening: This is a newer method of screening, where the dots are arranged in a random or stochastic pattern and have a fixed size and shape. The tonal value of the image is determined by the frequency or density of the dots. The higher the frequency, the darker the tone, and vice versa. FM screening is also known as stochastic screening or digital screening. FM screening is suitable for printing on textured or uneven substrates, such as fabric or wood, and for reproducing images with smooth gradations and continuous tones. FM screening can also avoid or reduce some of the drawbacks of AM screening, such as moiré patterns, rosettes, and dot gain. - Hybrid screening: This is a combination of AM and FM screening, where different types of dots are used for different parts of the image. For example, AM dots can be used for text and graphics, while FM dots can be used for photographs and illustrations. Hybrid screening can offer the best of both worlds, as it can achieve high quality and versatility in printing. However, hybrid screening can also be more complex and costly to implement than AM or FM screening. Screening is an important step in the printing process, as it affects the appearance and quality of the final output. Different types of screening can have different advantages and disadvantages depending on the application and requirements of the printing project. Therefore, it is essential to choose the right type of screening for each job and to optimize the screening parameters accordingly. Applications of Screening




Screening has many applications in various industries that require high-quality printing on different substrates. Some of the most common applications of screening are:


  • Printing on paper: Paper is one of the most widely used substrates for printing, as it is versatile, affordable, and recyclable. Paper can be printed with different types of screening methods depending on the purpose and quality of the print job. For example, AM screening can be used for printing books, magazines, newspapers, flyers, brochures, etc., while FM or hybrid screening can be used for printing photographs, posters, art prints, etc.



  • Printing on fabric: Fabric is another popular substrate for printing, as it can be used for making clothing, accessories, home furnishings, etc. Fabric can be printed with different types of screening methods depending on the type and texture of the fabric and the design and color of the print job. For example, AM screening can be used for printing on smooth and fine fabrics, such as silk or cotton, while FM or hybrid screening can be used for printing on rough and coarse fabrics, such as denim or wool.



  • Printing on metal: Metal is a durable and versatile substrate for printing, as it can be used for making signs, labels, tags, cans, bottles, etc. Metal can be printed with different types of screening methods depending on the type and shape of the metal and the content and quality of the print job. For example, AM screening can be used for printing on flat and smooth metal surfaces, such as aluminum or steel, while FM or hybrid screening can be used for printing on curved and textured metal surfaces, such as tin or copper.



  • Printing on plastic: Plastic is a flexible and lightweight substrate for printing, as it can be used for making packaging, toys, cards, etc. Plastic can be printed with different types of screening methods depending on the type and quality of the plastic and the design and color of the print job. For example, AM screening can be used for printing on rigid and transparent plastic surfaces, such as acrylic or polycarbonate, while FM or hybrid screening can be used for printing on flexible and opaque plastic surfaces, such as polyethylene or polypropylene.



  • Printing on wood: Wood is a natural and organic substrate for printing, as it can be used for making furniture, flooring, wall panels, etc. Wood can be printed with different types of screening methods depending on the type and grain of the wood and the style and tone of the print job. For example, AM screening can be used for printing on smooth and light-colored wood surfaces, such as maple or birch, while FM or hybrid screening can be used for printing on rough and dark-colored wood surfaces, such as oak or walnut.



Screening has many benefits for printing on different substrates, such as enhancing the image quality, reducing the ink consumption, increasing the printing speed, expanding the color gamut, etc. However, screening also requires careful attention and control to ensure that the screened files are compatible with the substrate and the printing device and that they meet the expectations and requirements of the customer. Therefore, it is essential to use a quality control tool like Esko Bitmap Viewer 10 to check and verify your screened files before you make plates from them.


Why Quality Control is Important for Screened Files?




Challenges of Screening




Screening is a complex and delicate process that involves many variables and parameters that can affect the quality and printability of the screened files. Some of the challenges of screening are:


  • Maintaining consistency: Screening can produce different results depending on the type of screening method used, the type of substrate used, the type of printing device used, the environmental conditions (e.g., temperature or humidity), etc. It can be difficult to maintain consistency across different files, substrates, devices, or conditions without proper calibration and adjustment.



  • Avoiding errors: Screening can introduce errors or defects into the screened files due to human or machine errors, such as incorrect settings, faulty equipment, corrupted data, etc. These errors or defects can affect the content or printability of the screened files and cause problems such as missing or extra dots, wrong colors, distorted images, etc.



  • Optimizing output quality: Screening can influence the output quality of the printed products by affecting factors such as sharpness, contrast, brightness, color accuracy, etc. It can be challenging to optimize the output quality without compromising other aspects such as speed, cost, or durability.
