T-shirt design printing: Choosing between screen printing and digital printing

Different techniques can be used to print your t-shirt design onto your T-shirt, and unsurprisingly, they produce different results. In this article, we examine screen printing and digital t-shirt printing, and the pros and cons of each one, to help you choose the best way to create your dream t-shirt.

Screen printing for t-shirts
If you had an industrious art teacher at school, you may have tried a simple version of screen printing in which a template for each color of your design creates the spaces where the ink can be pressed onto the fabric. The same principle applies in professional t-shirt screen printing, although there is more automation of the actual printing once the set-up has been completed.

Digital printing
This is sometimes called "direct to garment digital printing" or simply DTG. This technique involves the application of textile water-based inks to the t-shirt using a specialized digital printer The design is usually fixed onto the garment with a heat press.

Choosing the best t-shirt printing technique
When considering which technique to choose for a t-shirt print run, many people ask which provides the best quality finish. In fact, the best technique depends on the t-shirt design you want to print, as some are better suited to each technique. It also depends on the colors you are printing and the color of the base garment too.

The best T-shirt designs for screen printing
Bold designs with thick lines and few colors are best suited to screen printing, producing very high quality results. If you are using a digital image with fine color blending or black and white shading in your t-shirt design, screen printing will simply not be able to reproduce the image well.
Of course, other factors will influence the price of your t-shirt run, such as the number being produced, especially as screen printing does involve more setting up before printing can begin. The number of colors in the design also affects the price as a different screen is required for each color.
If your T-shirt design is relatively simple, screen printing may well be the best option as it produces a very high quality finish. Many in the t-shirt printing industry maintain that the best vibrancy of color can only be produced by screen printing.
The durability of screen printed t-shirts following multiple wears and washes is also considered to be the best, but of course, the quality of inks used and the base garment will also be a factor.

The best T-shirt designs for digital printing
Advances in printing technology have improved the finish of digitally printed t-shirts immensely over recent years. If you tried it a few years ago and were disappointed by seeing dots in your design, don't let it discourage you now. Modern digital t-shirt printing machines produce better finishes now, with better durability than ever before.
If you are using a photograph or complex, multicolored image in your t-shirt design, digital printing is the way to go as it can reproduce photo realistic designs. In addition, it's the cheaper option if you only need a small number of t-shirts produced as the set-up costs are lower.
One important factor to consider with digital printing is the color of the base garment, as generally that color is the most prominent in the design, and as a result, best effects are achieved using white t-shirts when printing a multicolored design. Only the very best DTG t-shirt printers may be able to get excellent results with black or dark colored t-shirts. Printing white ink can still be problematic, so avoiding using DTG t-shirt printing for designs that contain substantial white areas, especially on dark base garments, is a wise choice.

Summary

With the advances in digital T-shirt printing over recent years, it's no longer simply a case of "screen printing produces the best results" - instead, start with the needs of your design and examine whether screen printing or DTG digital T-shirt printing can best reproduce it.
In short, if your design is simple and has few colors, generally screen printing is the method to opt for, but may be more expensive for a small print run. If your T-shirt design involves many colors and photo realistic images, then digital printing should be your first choice. Of course, the best t-shirt printing companies will be happy to give you advice on what is best for your needs.

Computer Power Supply Unit (SMPS)

SMPS - Switch Mode Power Supply - is the technical term for what we generally know as the computer power supply unit. It is basically a box-like device used for the supply of power to your computer unit. So what does it do? In very simple terms, it converts the AC (Alternating Current) power supply from the general electrical sockets available at your home to DC (Direct Current), basically the type of current you get from a battery. The "Switch" term in the SMPS comes from the fact that the computer power supply unit converts AC to DC using switcher technology. We now use the ATX supply power units for the computers as the industry has settled on a standardized case and motherboard (ATX).

Typically, three voltages (12V, 3.3V and 5V) are supplied by the power supply unit.

If you are selecting a computer power supply unit, how do you go about doing that?

1. The first thing of course is to know what power requirements you are looking at. You can check the power requirements of the various devices of your computer and add them up, or you can just ask the vendor for the same. Once you have the total wattage, (that will be the unit of power), you can go for a slightly higher rated SMPS.
Now why you want to do that is because, at a later point of time, if you want to upgrade your computer, like a new DVD RAM drive, you may need a higher power supply.
One more thing to remember is to check the actual wattage against what the label on the power supply unit indicates.

2. It is always a good idea to go for a branded power supply unit. But that might not help if price is an important criteria.
The SMPS supplies power to all the components of the computer, like the motherboard (24/20 pins), hard drives and CD ROMS etc (IDE 4-pin), floppy drives (Floppy 4-pin), etc.
What happens is that, once the computer is powered on, there is a surge of current and as a result, it gets heated up. The fan, in such a condition is crucial, other wise, high temperatures might result. You should have at least one 80mm fan. It is even better if there are two fans instead of one.
(One such problem is the continuous restart of your computer as the temperature rise due to a faulty power supply causes the computer to shut down without giving any error message, and in some cases, not even the BIOS screen.)

If you have a branded SMPS, you can rest assured that there is not much chance of such an event occurring.

3. Number of connectors and the efficiency rating – These two factors are at par with the other factors while considering the computer power supply unit. The efficiency rating, is important as it is directly related to the heat output and subsequent temperature rise. Higher efficiency rating ensures that the SMPS causes a lesser rise in temperature.
The number of connectors is important as it determines how many devices you can use with your computer.

4. Lastly, the noise level – Apart from the CPU fan, the SMPS fan also determines the amount of noise generated – Except from a fine whirring sound, which is basically indistinguishable, you should not have any other sound coming from the SMPS.

Promotional Products – Create Competitive Advantage

There are many new ideas and products, nowadays that are used to create competitive advantages. In today’s corporate world it is must to stay competitive and keep all your employees and clients active and interacting with you. Different companies and corporates use different activities and ideas to keep the employees and clients in touch with them and let them participate actively with the company affairs; one of the best and widely adapted things to create competitive advantage is by giving away corporate gifts. The theme and the ways of doing business have been prevalent since the old days.

Before enumerating the advantages of the corporate gifts and how they help you in being competitive, let us give you an idea about what corporate gifts actually are. Corporate gifts are actually giveaways by the companies to promote their name and improve their image. Corporate gifts help companies in interacting with clients and other competitive corporates. These corporate gifts can vary considerably from promotional discounts and holidays and other facilities like free coupons and traveling tickets and free stays. Whatever you pick to offer as the corporate gift on behalf of the company, make it stand out in the crowd and do something that others are not doing. You must aim at offering corporate gifts that are not available in the local market.

Corporate gifts are used to challenge the competition and for withholding a strong position in the market competition. In the world, when we talk about corporate links and relations it is a must to maintain healthy and yet competitive relations with other clients and do your best not to lose the customers at any cost. These are the little things; if proper care is taken, then these would benefit the corporates with multiple profits but otherwise carelessness can easily ruin the profits overnights. So, one needs proper strategy and planning for offering corporate gifts.

Power inverter technology design advantages

DA Series Inverter and UPS inverter laptop battery conversion of comparison:

Telecom used the so-called inverter biggest feature is one DC power supply voltage is 48V, but by the power supply voltage of 48V converted the UPS inverter actually does not apply to communications systems.

First: DA Series Hp laptop battery of inverter input noise smaller. UPS work with the battery pack are used alone, did not consider the parallel battery use, so the UPS, there is no taking into account the communication system by the most sophisticated anti-irrigation input noise, the input noise greatly. If the UPS battery pack with its shared communication system, it will interfere with and affect call quality.

Second: DA series inverter with a specially designed DC snubber circuit. UPS generally only communicate snubber circuit design, that is, when the boot to prevent COMMUNICATION impact UPS, but in terms of communications systems is not enough, and Compaq Presario 2100 battery (compaq 2100 battery) are dangerous. Communications room because of the latitude cpx pack used, their capacity is generally more than thousands of AH, when the DC switch instant, batteries have a very easy to damage the surge of UPS components, battery life is also easy to wear and tear, it must be in battery pack and inverter plus a buffer between the start circuit to address the issue.

Third: DA Series Inverter UPS capacity than double the increase of the inverter. When the general UPS’s load at startup, in order to prevent computer capacitive loading effect of the cold boot startup date that Hp 319411-001 battery moment (about 10ms period) will have a tremendous load current, so boot jumper to bypass municipal electric supply. However DA Series inverter is not, when the load restart or cold boot, all cold boot the impact of the burden by the inverter, so DA Series Inverter UPS capacity factor of the inverter are the reasons for double In this. DA series inverter with Hp F4812A battery polarity protection. Battery capacity of the engine room are very great, if modified by the UPS inverter when the battery accidentally reverse connected, the UPS will not only damage will be to do permanent damage to the battery. However DA Series battery polarity protection, when an error occurs will not be able to start, to avoid the aforementioned problems.

Some users think the UPS with 48V inverter, in the normal situation, the machine’s power supply by the electricity rather than batteries, so it seems to reduce the burden on the Hp F4809A battery. In fact, for the communications room of the latitude c610 pack used, their capacity for thousands of AH in general more than usual by the communication switching power supply (the capacity of several hundred amperes) on the battery pack to float. So there is no need to worry about DA Series inverter battery pack will increase the heavy burden. Moreover, because of the industrial power network interference, distortion, mutation greatly, for peacetime use of electric-powered city forms of UPS inverter, its load will interfere with the inevitable impact of the good work load. At the same time, because of rectifier harmonic currents generated, the grid will result in anti-irrigation pollution, because the city of a sudden disruption in electricity, Hp F4098A battery supply current from zero to the great mutation will cause an instant latitude c640 voltage drop, while the DA series of communications-specific inverter with its job completely unrelated to the city of electricity, the electric city of interference does not affect the computer load. DA Series inverter inverter damage only in the use of bypass system to the city electricity supply load. Therefore the use of inverter usual job of the city is also the electric isolation, purification.
