A beginners guide to the application of computercut vinyl lettering

A Beginners Guide to the Application of Computer-Cut Vinyl Lettering

Detailed here are a couple of common methods you can use when applying computer-cut vinyl lettering to most substrates

Using a standard ballpoint pen mark a line on the substrate corresponding to the baseline of the text to be applied. Keep the line light so as not to cause an impression on the substrate. If applying to a vehicle or acrylic use a chinagraph pencil of a similar colour to the vehicle paintwork; some types of paintwork can be stained by chinagraph or ink so it would make sense to test it first in a discreet area.

Remove the text or logo from the release paper liner and hold firmly at each end. Line up the baseline of the text with the line marked on the substrate while keeping the text just away from the surface – you should be able to see the line through the application tape.

Lightly press the extremities to the surface to secure the text or logo in place. Using a specialist applicator (available from your vinyl supplier) press firmly from the centre out towards the edges whilst moving from the fold line out towards the end of the lettering or logo. Repeat the process working towards the other end.

Lift a corner of the application tape and peel back while keeping it as flat to the surface as possible; doing this helps to prevent the vinyl being pulled off of the substrate and also stops any paint being removed when the application is onto a painted surface.

Depending on what you have used to create the line it can be removed using meths, lighter fuel or alcohol spirit – make sure to test that it will not damage the substrate.

Hinge Method

Fold graphic in half and press a small fold into the bottom of the graphic. Place a piece of masking tape at each end of the graphic and secure to the substrate. Adjust the positioning until the fold mark in the application tape corresponds with the measured centre point of the substrate.

Working with one end at a time move the graphic until it’s baseline is the correct distance from the edge of the panel – you can use a tape measure or ruler to check this. Do the same to the other end and then re-check the first end as it will probly have moved.

When you are sure the graphic is in the correct position put a strip across the whole graphic somewhere near the middle and preferably with at least one edge lying in a gap between letters. This is known as the hinge.

Take a small piece of tape and apply to the substrate so that it butts up against the bottom of the application tape at the opposite end from the hinge. Remove the piece of tape, at that end, securing the graphic to the substrate and fold back the grahpic 180 degrees and press a sharp fold into it.

Peel back the release paper and tear it off at the fold line. Bring down the application tape towards the surface of the substrate while keeping it taught and line up the edge of the masking tape with the edge of the application tape. Using a specialist applicator (available from your vinyl supplier) press firmly from the centre out towards the edges whilst moving from the fold line out towards the end of the lettering or logo. Repeat the process working towards the other end.

Lift a corner of the application tape and peel back while keeping it as flat to the surface as possible; doing this helps to prevent the vinyl being pulled off of the substrate and also stops any paint being removed when the application is onto a painted surface. This method has the advantage of not needing any lines to mark the position and is therefore useful for applications to sensitive surfaces.

Where the graphic does not allow for a centre hinge, because of the lack of a suitable gap in which to create the fold, the hinge can be created at one end of the graphic or along the top or bottom.

Dvd replication without stress

DVD Replication Without Stress

The first step to ensure stress-free DVD replication is to go to a reputable DVD replication company that is communicative and descriptive about their services. There are a number of companies available and individuals should choose a DVD replication company that is reliable as well as easy to work with.

The next step to a smooth DVD replication project is to make sure that the medium being used is of good quality. This can often be a problem in DVD replication. An individual needs to make sure that the blank DVDs are of reliable quality. There are several reliable brands available and a lot of them are not too expensive.

Very often the quality of the DVD is poor because the medium being used was faulty. Physical defects, especially those on the disc’s photosensitive layer, will cause recording flaws in DVD replication.

Sometimes errors also occur due to dust and particles in the computer and the surface of the DVD duplicator. An individual needs to remember to clean the DVD duplicator with a soft cloth before loading the disc for DVD replication.

It’s also needed to make sure that their software is updated frequently. This will allow the DVD Equipment to get the best out of their DVD replication efforts. A common reason why DVD replication does not work is because the computer does not have the right software installed on it. A reputable DVD replication company will be using the latest technology so the individual won’t have to worry about such things.

People who are looking for good quality DVD replication must not rush things. DVD replication works best when they are done by good reputable DVD replication companies such as VE Associates.

Design concepts of uninterruptible power supplies

Design Concepts of Uninterruptible Power Supplies

The design of the Uninterruptible Power Supply is determined to a large extent by the required function and what level of critical cover is expected to protect the load .
At the bottom end of the scale are ‘ Desk Tops’ the Offline UPS system , generally below 1kVA, as its name suggests it provides an unregulated filtered supply to the load at the same time maintaining the state of charge of the battery by a separate charger.
When the utility mains fails or goes out of tolerance the inverter turns on and is connected to the load via a relay. There is a short break while this operation takes place and the duration of this break is called the transfer time.
The Offline UPS system is not suitable where there are large variations in the local utility mains supply, as the load will be directly affected. To overcome this problem a Line Interactive UPS system can be used, the technology operates in a very similar way to the Offline UPS systems whereas the inverter does not provide supply to the load unless a utility mains failure or brownout has occurred.
The Line Interactive UPS system uses an active voltage regulator (AVR) to control the voltage seen by the load during normal operation; this method insures that the load has a constant voltage applied to it. Again these Uninterruptible Power Supplies are more suitable for smaller office environment loads and generally are restricted to a maximum of 10kVA.
Traditionally for larger load requirements the Double Conversion UPS system has been favoured, basically it consists of a rectifier, battery, inverter and static switch. This is generally termed- True On-line UPS -
The term ‘True On-Line’ is used because this type of UPS will really protect your mission critical equipment to the point that if you remove its power source and then re-instigate the power , there will be no effect on your equipment.
How is it work then? The True On-Line Uninterruptible power supply works by having a rectifier, which converts the utility mains ac supply to dc, has the dual function of providing a dc supply for the inverter and also a supply to recharge the battery. Therefore in the event of the utility mains failing or going out of tolerance due to voltage or frequency causing the rectifier to switch off the battery will seamlessly continue to provide the dc supply for the inverter.
The inverter then converts the dc supply back to an ac supply that is voltage and frequency controlled to supply the load. The load is therefore completely protected from any surges, spikes or sags from the utility mains supply.
The double conversion Uninterruptible Power Supply has the added advantage of what is generally called the static switch; this is an electronic changeover power switch, which selects the supply required for the load. The supply can be either the unprotected utility mains supply or the fully protected inverter supply. This feature can be very useful in the event of an overload occurring, which is beyond the rating of the inverter, the load will be automatically transferred without loss to the utility mains supply, transferring back to the protected inverter supply when the fault has been removed.

What is wireless internet and how can i get it

What Is Wireless Internet And How Can I Get It?

Wireless Internet has truly changed the way the world goes online. Because of this transformative technology, you can go online and enjoy high-speed Internet access without being tied down to your home. In fact, wireless Internet is so wonderful because of the freedom it gives the individual to surf online away from the desktop, on your laptop or other portable device.
Also referred to as “wifi,” wireless Internet is usually accessed on a laptop, cell phone, and other mobile computing device. You can also set up a wireless network between the computers in your house using a special router. People use wifi at home as a way to wirelessly access the Internet from any room in the house. It really is the most convenient way to go online in the modern world.
Wireless Internet providers offer a wide range of services to customers with speeds that compete well with DSL and cable. In the past, before the introduction of wireless Internet and routers, the only way you could connect to the Internet on your laptop was through a very slow, dial-up connection. Luckily, wireless Internet now allows you to go online without having to plug into a phone line.
Connection speeds for wireless broadband vary between 384 Kbps and 2.0 Mbps, which is a whopping 35 times faster than your average dial-up speed. This allows users of mobile devices to carry out online tasks on the go – and you can do more than just email and text message. Plus, it allows you to wirelessly set up a network at home with the use of a router.
Wifi and wireless routers make it possible to download streaming media and large files no matter where you happen to be – this is a convenient option for media junkies who just can’t get enough of online media, such as videos. This type of router in particular lets you share files between several computers at home. In the past, you had to create a wired network for this to work – now routers make it possible to network more than one home computer more easily. Wireless routers let you bridge several computers together, even in different rooms.
How it works is that you purchase a wireless Internet connection, and then set up a router to transfer the signal elsewhere, and share the Internet connection.
With a laptop and router it’s easy to get connected to a wifi signal and take advantage of wireless broadband – almost every laptop sold now comes with a wireless modem already installed. The same goes for portable handheld devices, which have wifi capabilities built right in. The number of wifi hotspots is also increasing, so you can almost always find access to a broadband connection when you need it.
So where do you find a wifi provider? If you want to find a broadband connection in your local area, that isn’t in your home or office, all you have to do is search online for hotspots that provide wireless Internet service. There are various websites that help you locate broadband connections in certain areas, especially as wireless Internet access grows in demand.
A wifi connection doesn’t have many requirements. Although different from other connections, providers do provide many of the same features provided by other services. A wireless Internet service usually requires a laptop computer or a computer that is connected to wireless routers. A regular computer may need a Wi-Fi card for the service to work properly.
For wireless Internet access you may also need sniffer software that allows you to search out hotspots around your town.
