Speedball Screen-Printing Inks are water-soluble, non-toxic inks. They are perfectly safe to use in print studios, homes, schools, and industrial settings. They dry to a smooth, matte finish that is still water soluble. Because they are water-based, they can be cleaned up with water or detergent.
Printer ink is not hazardous to the touch, but it should not be breathed. All inkjet printer inks are made out of water, alcohol, and ethylene glycol, with additives added to achieve varying strengths and consistencies. These additives include dyes, humectants (moisture-absorbing substances), and solvents. Inks can dry out over time, which can cause problems with nozzles on print heads; you may see print defects such as streaks when this happens.
Inkjet printers shoot drops of liquid colorant onto paper to create images. These drops can be either solid (such as black) or vapor (such as cyan). With multiple colors used together, printers can reproduce any image in the rainbow. For best results, use ink that is labeled for your specific printer type and read your printer's instructions before starting work.
All ink contains some amount of solvent, usually ethanol or propanol, to keep the ink fluid at room temperature. Too much solvent can lead to blurry prints due to evaporated layers of ink underneath other parts of the print. However, many printers are now using alternative solvents such as hexane instead of ethanol or propanol because they're considered safer to breathe in case of spillage.
Liquid printer ink is not hazardous to the touch based on these chemicals. The rare leak while changing cartridges should not be reason for concern, and the deep ink stain generally appears much worse than it is. The dye in the ink will break down over time into less harmful substances.
Inkjet printers use tiny drops of liquid ink that are sprayed onto paper. The ink contains a colorant (usually black or white) that reacts with water to form small particles that are dispersed in the paper. These particles make up the image. Black ink also includes an agent to prevent it from drying out before it gets to the paper.
The printhead of an inkjet printer consists of an array of channels through which liquid ink is delivered and ejected as drops by a series of pressure pulses from a piezoelectric device called a "printhead cartridge." Each channel includes a nozzle through which droplets are released. In most cases, each channel leads to a common point where all the channels meet; however, some types of printers have separate points for each channel.
When you lift off the lid of the printhead cartridge, you are actually lifting off the top layer of the printhead. Below this top layer is an assembly that has multiple layers including a membrane that defines each of the channels.
A home iron can be used to cure Speedball water-based fabric inks. Examine your iron settings in relation to the fabric you printed on. Only use textiles that can withstand temperatures ranging from 275 to 375 degrees Fahrenheit. If you print on cotton, use a medium heat setting.
The curing process removes moisture from the ink, making it less likely that it will smear when pressed onto fabric. Curing is also necessary to prevent further oxidation of any remaining dyes in the ink after exposure to air for a period of time.
There are two ways to cure an ink stain: by hand or with a dryer. Curing by hand is slow and should be done under daylight conditions for best results. Curing in a dryer speeds up the process but may cause damage to some fabrics. Only use heat safe materials when drying ink stains.
Ink stains can be hard to remove completely, but there are several methods for removing home-made and commercial dye stains from clothing. The most effective method depends on how long the ink stain has been there. If it was just last week, try one of these methods: washing with soap and water, taking the item to a laundromat, or using a commercial stain remover.
Ink contains chemicals that can irritate your stomach and intestines. If you do decide to eat any ink after it has been in your refrigerator or freezer, only eat a small amount at first and then wait at least an hour before eating more.
Ink contains heavy metals like lead and mercury. While relatively harmless when eaten, if you were to swallow solid lead it could cause damage to your digestive system. If you drink liquid lead it could be toxic. Hanging on to your old printed materials may also allow you to come into contact with this metal which can be dangerous. Avoid touching your tongue to a pin while it's covered in ink; even though the ink is not currently visible, it can still be activated by heat from your body.
Ink contains solvents such as benzene that can dry out your mouth and throat. If you're exposed to these chemicals for long periods of time, they may cause problems with your lungs. Print shop workers are likely to be exposed to these chemicals on a daily basis. They need to take special precautions because the skin around their mouths will constantly be wet from spitting out solvent-based inks.
Speedball's Oil-Based Block Printing Inks are made from high-quality pigments and are designed to be permanent, waterproof, and archival. Speedball Oil-Based Inks are available in six vibrant colors and may be used to print on paper using any traditional printmaking surface. They are also useful for creating artwork for walls and furniture.
Toner, which is used in laser printers, is non-toxic as well. Toner, like liquid ink, should be avoided in the mouth and eyes, but it is typically safe for its intended usage. When the toner is fused into the paper during the laser printing process, ultra-fine hazardous particles might be emitted. These particles are considered inert and are not harmful.
In fact, most toners include a fungicide to prevent fungal growth in furniture made from wood pulp. This means that they are environmentally friendly too!
However, you should still avoid eating, drinking, or smoking when working with toner, just in case. It's best to take precautions when using materials that can cause harm if used improperly.
Toner has a very long life span; you should expect to use up to half of its content each time you print something. Thus, it is important to choose high quality toner that does not need replacement so soon after purchase.
If you are worried about the toxicity of laser printer toner, there are other options available on the market these days. E-ink printers use liquid crystals instead of ink cartridges, for example. They work by applying voltage to glass plates coated with a special material that changes orientation when exposed to electromagnetic radiation from the printer's head. This causes the plate to either reflect or absorb light, depending on the applied voltage level.
