Digital printing is ideal for small orders where multiple colors and customization effects or photographic images are a must. However, digital printing may not be suitable when customers need to print light-colored materials if the printer does not use white ink.
The other major downside to digital printing is that it is not only as durable as screen printing, but is a perfect solution for unique events and unique displays. And lastly, you won’t save on printing costs if you opt for digital printing, as the prices stay the same regardless of how many prints are required.
Common faults of digital printing
Quality printing has indeed come a long way since its inception. Even with the beautiful technology that assists professionals in printing tasks around the world, flaws can still occur. That’s not to say the pros don’t know what they’re doing.
Mechanical defects mainly cause these problems with digital printing. Some of the main shortcomings of digital printing are as follows:
1. Large volumes are expensive
Digital printing machines operate at a maximum of about 50 feet per minute without getting too technical. While this speed is adequate for a modest volume (10,000 to 15,000 items), larger volume jobs will benefit from traditional presses that can operate at speeds between 300 and 500 meters per minute.
Even if Canon Large Format Inkjet Printers are not expensive to set up and operate, they will save you money if your work is very important.
2. Ink restrictions
While digital printing undoubtedly works well with color and ink, digital inks tend to fade faster than offset inks when exposed to direct sunlight.
Also, the opacity of digital ink is not quite equal to that of offset ink because digital ink is naturally thinner (although the difference between the two is only noticeable when it is these are transparent or metallic supports).
There are kinds of laminates available to avoid this problem. For this purpose, Canon large format inkjet printers are the option.
3. Registration errors
Have you ever seen a photo that shows a solid color at the edge of a colored image? This is often an insufficient registration. Suppose the shades that were printed upside down do not line up.
In this case, you get some weird “special effects” including double images or a solid colored line at the edge of an image or text. This is often a sign of a digital press maintenance problem.
4. Strips of solid and prominent areas
Stripes occur when the “stripes” are evident on your printed sheet. Sometimes there are bands in huge solid sections printed with more or less ink due to different issues. Every digital printer manufacturer has a technical limit on how large a concrete color area can print reliably.
It can also be caused by the paper moving quickly through the printer, tilting the media, or preheating too high. But for Canon large format inkjet printers, this is not the case.
Colors differ between printers. It is not easy to match colors correctly on prints created by various printers.
However, this is common because different printers interpret your color settings differently. While this does not properly solve the problem, Canon large format inkjet printers can reduce inconsistencies.
6. Fold the cracks
The toner is on the paper in digital printing and does not penetrate the ink in offset printing. As a result, the toner cracks when digitally printed parts are folded. There are several strategies to remedy this: use less toner or mark the paper before printing.
If you use less toner, you won’t crack as much. Before printing, the scoring of the sheet gives the toner a predetermined shape to rest on before folding and can help prevent cracking.
Digital inks fade faster in direct sunlight than flexographic inks or offset printing. Each ink fades over time. It’s just a little faster with digital ink. If you want the ink to last over a decade, have your label screen-printed.
Special laminations for UV inhibitors help ink survive longer as an option. Most items are used up long before the ink starts to fade.
8. Low opacity
The digital press can print in CMYK a little better than a conventional flexographic label printer. However, there are several restrictions on duplicating spot colors. Mixing spot colors on flexo presses is easier.
The opacity of digital press inks is not as high. The ink is a bit finer than a flexographic press. Only transparent or metallic materials are visible. However, a bump or two of white initially laid will almost remove this concern.
9. No dark colors and belt drive
Digital printers are not capable of producing light colors or white printed on darker colored paper. You will need to print to Canon large format inkjet printers if you are printing white on blue or black paper.
The belt typically drives digital printers. After the paper leaves the drawing box, it lies flat on a belt while the machine is fed. This may cause a slight lag between prints. However, it is very low and does not impact the printed job.
10. Poor color quality
As versatile as commercial digital printing can be, its drawbacks need to be properly considered. First, the color quality is not as high as in offset printing. Digital printing uses a CMYK method – a unique combination of cyanine, magenta, yellow and black to bring your artwork closer to each color.
11. Color absorption
Another problem with digital printing is that the color is not absorbed into the printer paper as in offset printing. It helps to leave cracks in the ink when printed parts are cut or folded. Digital printing may therefore be a less ideal alternative for brochures, greeting cards and other folded items.
12. Combination of new and old technologies
Digital printing technology continues to improve, printing speed is accelerating. However, there is still a long way to go to catch up with the pace of traditional printing.
Thus, the rapid use of the digital press for proofing or in small quantities, in combination with the traditional press for mass production, would for a time be a basic combination mode for the textile printing industry. And we need to create future breakthroughs by combining new and old technologies with complex situations.
13. High ink cost
Digital inkjet printing incurs a small number of overall production costs compared to traditional printing. Because color and pigment ink are cheaper than traditional printing are significantly more important.
14. Color accuracy
Compared to conventional spot color printing, each color set independently adjusts the color paste. We can achieve high color accuracy by computer color matching system. Even though the color paste is different, it only impacts one color on the printer paper.
Digital printing is a mixture of CMYK colors; each color is mixed with a tint of four colors. A small external effect, such as ink difference, print head difference, and small changes in the printing process, will affect the accuracy of many colors. The color accuracy of digital printing is therefore slightly lower than that of traditional printing.
The popularity of digital printing has undoubtedly increased in recent years. Digital printing accounted for 16.2% of the value of the global printing market in 2017. Due to its growing popularity, many believe that digital printing is the best option, which is not always the case. .
Digital printing is not the right choice for everyone. It is suitable for minor work using non-exotic media. But with Tenaui Middle East, standard offsets are a better alternative for big, urgent jobs. It is imperative to consider the pros and cons of each option before choosing how to print. So if you make a choice, you’ll be sure it’s the right one.
