When producing print, the question of quality is key. What quality should I produce, what quality is the customer expecting, what quality is appropriate? The answers to these questions are not always what you’d expect. Printing with the emphasis on speed can run the risk of the work being rejected or reprinted, however, producing with high-quality settings can tie up the printer's capacity for unnecessary amounts of time.
It would be great if we could print at lightning speed and still achieve crystal clear quality, but reality doesn’t always work that way. In fact, selecting productivity settings over quality is not even a bad thing – as you’ll learn, sometimes it’s better to print higher volumes than it is to print ultra-sharp quality.
First, what do we mean by quality?

It’s not all about the printer
Whether you focus on resolution, dots-per-inch, halftone screening or droplet sizes, in general, when we talk about print quality, we are referring to the printer’s ability to reproduce an image accurately and with clarity.
As a business owner, you should consider other factors which fall under the category of quality. Is your adhesive vinyl applied without creases or bubbles? Does your printed output stand the test of time without fading or rubbing off? Can your employees accurately produce a customer's order without making mistakes or taking obvious shortcuts?
When we consider the service you offer, many customers might not have a trained eye for color accuracy. They don’t care about the size of the ink droplets as long as you can satisfy their needs. They just want good products from a reliable company in a timely fashion and at competitive prices.
Quality vs. Speed
Practically speaking, if the printed output is designed to be seen from a distance – for example, with banners or billboards – a focus on photographic style reproduction and smooth color tone would be unwarranted. You can print these products at high speeds with a lower print quality and produce a high volume of work, while keeping your prices competitive for the customer and maximizing the production capacity of your print equipment.
When printing panels for exhibition stands, POP displays, and projects which are likely to come under closer scrutiny from more people, you'll want to use higher quality settings. Roland DG's new TrueVIS XP and XG series eco-solvent printers and printer/cutters offer both speed and quality, so you don't have to sacrifice time while producing the high-quality results your clients need.
What factors impact quality?

1. HARDWARE
As a print service provider, your printer is the heart of your business and it’s an important investment decision to make. You should look for high-specification print heads with a good reputation for reliability and longevity, always ensuring the print nozzles fire correctly and accurately.
You should also look at the overall build quality of the device and ensure that the media is handled well and stays in place while the printer does its job.
2. INK
The quality of your ink will determine the overall quality of your printed images as well as their durability. If you want to ensure consistent results across time, without constant recalibration and unexpected surprises, it pays to use only ink certified by the manufacturer of your device. While cheaper inks might save you money today, the long-term impact could be catastrophic for the future quality of your service and the reputation of your business.
Higher-grade inks are also more likely to feature additional performance characteristics such as colou=r consistency and optimal drying, enabling faster finishing and shipping.
Not only does this speed up production and offer faster turnaround times, but it reduces the chances of accidental smudging or contamination. Of course, with technologies like UV ink, this is less of a concern as the ink is cured instantly with UV lamps built into the print carriage.
3. MEDIA
As with hardware and ink, with media, you get what you pay for. For temporary signage jobs, you can get by with a budget option, but for more permanent solutions, or high-profile jobs for larger clients, it pays to invest in media you know will show the print off to its best potential. It’s also important to use the right media for the job and ensure that it will withstand the environment into which it is placed.
4. IMAGE RESOLUTION

Always ensure that your source imagery is of a high enough resolution, especially when printing larger applications. Vector-based graphics and text can usually be scaled without any loss in quality, but raster images like photographs have an upper limit after which the pixels become clearly visible. In the latter case, using the highest print quality settings can even be detrimental as it can expose imperfections with much greater clarity.
5. MAINTENANCE
Don’t overlook the importance of regular maintenance and periodic service checks. Nine times out of ten, a chronic issue in print quality is the result of an insufficient head cleaning schedule rather than the device itself. A quick and simple maintenance cycle lets you keep your print heads and nozzles in top condition without impacting productivity.
Of course, no machine is invincible and sometimes wear and tear can create issues that you can’t repair by yourself. In these cases, it makes good business sense to work with a manufacturer that can offer warranties with comprehensive service so your production isn’t interrupted.
6. CALIBRATION
If you’re not getting the level of quality you expect, there’s a chance that your printer isn’t properly calibrated. Perhaps you’ve switched to a thicker media, or a heavier roll in the case of roll-to-roll printing. Perform a test print to check your bidirectional alignment and ensure your print is correctly profiled for the media you are using.
7. ENVIRONMENT
Occasionally, the biggest enemy to perfect print has nothing at all to do with the printer. It’s not uncommon for dust, lint and other contaminants to float around in your print room and cause unwanted effects. Sometimes these particles will stick to the media before printing, and sometimes they’ll land on the print after it has come out of the printer.
Either way, they can create small imperfections which can ruin the effect of the full print, especially in wide areas with solid colors. You can get around this by keeping your print room and media storage area free from dust and providing adequate ventilation.
Sometimes, the temperature of the environment can also affect the viscosity of your inks and cause fluctuations in the print quality. Temperature and humidity can also create more static which can affect the accuracy of the print. To maintain consistency, you should try to ensure that the mean temperature and humidity are regulated.
8. EXPERTISE
Even when everything else is working as it should, human error can often lead to insufficient quality. Digital printing has made print processes a lot more user-friendly, but without proper training, it’s easy to miss something and produce substandard output.
Ensure you provide comprehensive training for all your employees so they can produce the expected quality at the right speed. Also, check with your manufacturer and see which training options they offer. Chances are they can explain time-saving RIP features and help you set up tailored workspace settings, which can substantially speed up overall production and reduce errors.
