1. What is digital printing and how is different from other forms of printing?
Digital printing is a method of printing using digital techniques in which data and images are printed directly from a computer onto paper or any other suitable medium or substrate. A simple example is the familiar digital printer (also referred as ink-jet printer) used in homes and offices for printing documents and photo-quality images. Ordinary screen printers and rotary printers are on-contact printers, while digital printing is an off-contact printing.
2. What are the advantages of a digital printer?
A digital printer offers tremendous advantages over traditional printing techniques. Very high resolution, real-life like pictures, ability to print on curved, uneven or textured surfaces and customized solutions are some of the advantages of a digital printer.
3. How is a digital printer able to produce so many colors on a single tile? Why can’t many colors be printed with traditional screen printing technology?
The digital printer is based on the CMYK color process. Four colors – cyan, magenta, yellow, and black, abbreviated as CMYK are combined in various ways to create virtually any color required. In the traditional screen printing process, one screen is required for each color and not more than 3-4 such screens can be employed on a typical glazing line thus limiting the number of colors to maximum of 3 or 4.
4. How does a digital printer work?
The heart of any digital printer is the printer head. Every print head contains hundred of tiny nozzles through which a measured quantity of ink is ejected out. Piezoelectric crystals present in the print head nozzles vibrate at desired frequency and eject precise amounts of ink droplets. Hundreds of such nozzles work in tandem to create millions of such drops or dots that together combine to form the desired design or image.
5. What kind of inks are used for printing?
Digital printers used for printing on paper use organic solvent based inks. The inks used for digital printing on tiles is a special formulation and is made from a suspension of extra fine inorganic pigments.
6. What kind of designs and images are available in the Johnson Digital collection?
The Johnson Digital collection comprises of marbles with extremely high level of detailing printed on flat and relief surfaces, wood designs that replicate real wood, photographic images with vivid real-life pictures etc.
7. Since digital printers allow for customization, how can one order for customized designs?
Subject to certain minimum volumes, customized designs can be developed and manufactured as per the requirement of clients. The design to be customized needs to provided in digital forms with a high level of resolution that would depend on the size of the image to be printed on the tile.
8. What is Germfree tile?
Germfree is yet another innovation from H & R Johnson (India) and is ideally suited for today’s health conscious consumers. The Germfree tile is manufactured using a specially formulated anti-microbial glaze and is soon to be patented. This special glaze inhibits the growth of germs, bacteria, fungus, and other microbes that come in contact with the tile thus contributing to a healthier living environment.
9. What is the mechanism and technology behind the Germfree property?
The Germfree glaze consists of Nano-sized (one millionth of a millimeter) Silver cations. In the. Presence of moisture, silver cations are leached in to the atmosphere. The cellular protein present inside the bacteria and microbes have a high affinity for metal ions such as silver. The silver ions thus leached form a strong molecular bond with these cellular proteins that bacteria use to respire. This bonding of the protein with the silver ions disrupts key cell functions, disabling the bacteria from growing or reproducing, eventually leading to its death.
10. Do all tiles in the Johnson digital range have the Germfree property?
Yes, the entire collection is manufactured using the specially formulated anti-bacterial glaze.
.11. What are the application areas for the Johnson Digital range?
All places where either beauty or health or both are required. This may be homes, offices, schools, hospitals, malls, airports, and virtually everywhere where human beings inhabit.
12. In bathrooms where wall and floor tiles need to be used, does Johnson provide coordinated floor tiles to support the digital wall collection?
For wet areas such as bathroom applications it is important to have an antiskid tile on the floor. Johnson has developed an exclusive range of anti-skid floor tiles that are ideally suited for bathroom use in size of 600 x 600. These tiles have textured surfaces or projections to break the film of water or oil found in wet areas, thereby increasing frictional resistance between the tile and feet.
13. Do the 600 x 600 antiskid tiles have the Germfree property like the Johnson digital collection?
Yes, the coordinated 600 x600 tiles besides being anti-skid, are glazed with the same anti-bacterial glaze to protect your floors from harmful bacteria.
14. Are the Johnson digital range and the 600 x600 anti-skid tiles rectified?
Yes, the entire collection is available in rectified format to minimize joints and for maximizing hygiene.
15. What kind of grouts are best suited for use with the Germfree wall and floor tiles?
We recommend the use of BAL Endura epoxy grouts for filling tile joints. Due to their intrinsic physical properties, these epoxy grouts inhibit the growth of bacteria in the joints.
