    en.wikipedia.org/wiki/Screen_printing

    Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.A blade or squeegee is moved across the screen in a "flood stroke" to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.

    For small-format printing, inkjet has also become the dominant technology, though special dye-sublimation transfer laser printers are also available. [6] In order to transfer the image from the paper to the substrate, it requires a heat press machine process that is a combination of time, temperature, and pressure.

  6. Surgical mask - Wikipedia

    en.wikipedia.org/wiki/Surgical_mask

    A surgical mask serves as a mechanical barrier that interferes with direct airflow in and out of respiratory orifices (i.e. nose and mouth).Most commonly used surgical masks are designed to only trap respiratory droplets, and therefore do not filter or block fine airborne particles that are smaller than the designed filtration ratings, which may be transmitted by coughs, sneezes, unintentional ...

    Open Artwork System Interchange Standard (OASIS [3]) is a binary file format used for specification of data structures for photomask production. [4] It's used to represent a pattern an interchange and encapsulation format for hierarchical integrated circuit mask layout information produced during integrated circuit design that is further used for manufacturing of a photomask.

  8. Simple face mask - Wikipedia

    en.wikipedia.org/wiki/Simple_face_mask

    The simple face mask can deliver higher flow rates than nasal cannula (6–10 liters per minute) for an FiO2 of 30- 60% oxygen. [1] Nasal cannula and simple face masks are described as low flow delivery systems. [2] [3] Unlike the non-rebreather and partial rebreather masks, the simple face mask lacks a reservoir bag.

  9. Respirator - Wikipedia

    en.wikipedia.org/wiki/Respirator

    A surgical mask may not block all particles, due to the lack of fit between the surface of the face mask and the face. [48] The filtration efficiency of a surgical mask ranges between 10% and 90% for any given manufacturer, when measured using tests required for NIOSH certification.
