YOU TOO CAN EASILY TEST A SCANNING FLUID FOR EQUIPMENT SAFETY
         Significance of the Cup Test
  • Polystyrene foam like the canary in the mine: Like scanner drums, it is highly susceptible to attack by aromatic
    hydrocarbons in some scanning fluids. These are the same substances that damage legacy films by
    extraction of the plasticizer, which cause embrittlement and fire danger, which Lumina does not contain:
    Lumina is totally free of aromatic and cyclic hydrocarbons that can compromise drums an film. Additionally
    aromatic hydrocarbons are more toxic.
  • A scanning fluid that passes the cup test, is safer for film and scanner drums.
For this Test  you need
  1. Cups as used for hot drinks
  2. Two jars a bit wider than the bottom of
    the cup to support the cups during the
    test.
  3. Saran Wrap to cover the cup to prevent
    evaporation of the fluid during the test.  
  4. About 2 oz (60 ml) of  scanning fluid.
    Doing The Cup Test
  1. Sit the cups on the jar
  2. Pour the equal amounts of fluid in the cups
  3. Cover both cup and jar with clear plastic Wrap.  
  4. Allow to sit overnight or longer
  5. Inspect the cups and compare then with a new cup.

A CHEMICAL EXPERT VIEWS  ON SCANNING FLUIDS
Are any scanning fluids
"NON -TOXIC" ?
NO! All scanning fluids are petroleum distillates and all are
TOXIC.  There are no exceptions! But the degree of toxicity of
scanning fluids can vary a great deal.
Respiratory toxicity increases with volatility and the %  of aromatic
hydrocarbons in the mixture.
Beware of information sources that claim that any product consisting of
petroleum distillates is non-toxic. This is simply not true.
Reliable sources of toxicity data are among others National Institute of
Safety and Health (NIOSH), USA.
Can a fluid be detoxed by
adding odorants ?
NO!  An odourant kills the smell but it is not the smell that kills you: Carbon
Monoxide is odorless but can kill you.
Smelly Stuff
Can be Indicative of strong solvents that can extract plasticizers (Tri-Phenyl
Phosphate) from legacy films),  and damage equipment such as the Epson
Fluid mount tray. Smelly stuff can be indicative of a higher health hazard in
the environment it produces smog, and is ecologically unfriendly,
During storage can oxidize  and become oily, leaving residues on film.
n-Hexane
Some scanning fluids contain n-Hexane. It is a neuro-toxin that damages
the nervous system of frequent users who inhale it.  LUMINA is free of
N-Hexane.
Flammability look for
Flash Point
Higher FP = Safer
Lower FP = Less Safe
FP Below RT:
beware!
FP is a measure of flammability. Ask your supplier for the LAB  measured
Flash Point. Do not rely on makeshift tests.
All hydrocarbon fluids have a flash point.  If heated they may reach the
temperature at which they can cause fire or explosion.
A safer scanning fluid is one whose Flash Point is higher than room
temperature. Indoor use of low flash point fluids poses serious risk, and
may void your insurance.   
It is a sound practice with all organic substances to minimize inhalation.

                                         ADVANCED TECHNOLOGY
                                                  OPTICAL FLUID

                  IMAGING FROM FILM

        Relatively Simple process
        Easy repetitive iteration or editing.
        Original needed the first time only.
        Identical second generation duplicates

     Optical Limitations of DRY Imaging from Film

        Light going through dry film is subject to some Scattering at the film grain. Consequences:
        Lower contrast
        Emphasized grain
        Reduction in color saturation
        Over emphasis on scratches and dust
        Reduced dynamic range
        Limitations shared by analog and digital methods but can be overcome for both.
        Film Curvature
        Correction requires glass: negative consequences:
        Additional refraction, -Loss of sharpness and contrast
        Use of Anti Newton Glass: Loss of sharpness and contrast.

     Optical Advantages of FLUID Imaging from Film

        Elimination of air / film interphase
        Elimination of Light scattering at grain =
        Higher contrast
        Greater sharpness
        Higher fidelity rendition of grain
        Higher color saturation
        Dust and scratch-reduction or elimination
        Rich gradation

     PHYSICAL Advantages of FLUID Imaging from Film

        Film Flatness = Uniform plane of focus
        Glass needed only on one side
        Glass can be placed in non-refractive position
        On side of light relative to film’s emulsion
        Avoids Anti Newton Glass

     The Ideal Imaging Fluid

        Causes no physical damage to Film or equipment
        Not a solvent: Does not dissolve film backing or emulsion or drums, if drum scanned.
        Chemically inert under use or storage conditions
        Try the ScanScience Cup Test.
        Odourless

        High Flash Point
        Non toxic?
        No such thing, all hydrocarbons are toxic by ingestion
        

     Imaging Fluids: Special Concerns with Legacy Film

        Many Film variants
        Nitrocellulose > Other cellulose backed films containing aromatic plasticizer: Tri-Phenyl Phosphate (TPP)
        Fluids containing aromatic hydrocarbons can extract the TPP : cause dimensional changes to film, increase
          brittleness.
        Try ScanScience Cup Test: tests solvent aggressiveness of fluid against Polystyrene a polyaromatic polymer.
        Fluids that damage polystyrene can also extract TPP and may damage scanner drums

     IMAGING FLUIDS EVOLUTION

        Developers of the Drum Scanner run Into Newton, Rings, they knew those could be eliminated by fluid mounting.
        These guys tried baby oil, and it worked.
        The first generation imaging fluid was born!

     Results were great...

        But the drudgery had begun.
        As It turned out, baby's bottoms were better with oil, not drums.
        Cleaning the drum required nasty, volatile and smelly stuff.
        If it were possible to eliminate the cleaning that would be great!
        There had to be a better way.  A Better way?

     A better way? Really?

        Why not use the smelly volatile stuff used for cleaning the scanning oil as the scanning fluid.....
        Voila, it evaporated after use no cleaning needed!
        The Second Generation imaging fluid was born!
        The cleaner, now the scanning fluid:  the smell was the same, bad.
        Ah! but a great time saver. That was real progress.
        With the second generation scanning fluids Baby Oil went back to being baby oil and
        The cleaning drudgery was gone.

     All That Happened In.... THE LAST CENTURY

        Not bad for empirical DIY.

      Primary on Newton

        Light that strikes two reflective surfaces in close proximity and a slight angle to each other yields two wave fronts
          which reinforce each other when in phase or destruct when out of phase.
  
            each other when in phase or destruct when out of phase.
        The result is a series of lighter or darker rings.
        If the reflective surfaces are kept parallel, the resulting wave fronts are both in phase: therefore, No Newton rings!
        But, glass, if used to flatten film is a refractive element that degrades the image. A trade off.

     Avoiding Newton Rings A better way

        Filling the air space between the two reflective surfaces with a fluid:
        Forces the film into a flat plane
        Eliminates the air space between reflective surfaces, makes the surfaces parallel and banishes Newton Rings.
        Without fluid scanning, drum scanners could have not become a commercial reality.
        The same technology is available to all scanners

     Oil-type Imaging Fluids Pros

        THE PRO’S
        Scanning Oils are practically Chemically inert to film and scanner drums.
        The Oils high molecular contributes to their low volatility and solvency.
        Oils have no tendency to flash off at the edges of the fluid mount.
        Oil-type Imaging Fluids
        Scanning Oils are stable in storage because they are devoid of the reactive and smelly components natural to less

   
            pure petroleum   hydrocarbons
        The Oils low volatility  means no vapours released
        Oils  are essentially not flammable.  Big plus!
        The Oils high viscosity and low volatility help maintain a good temporary bond between the components of the fluid

   
            mount. No flash  off.


     First Generation Scanning Fluids

        That was the good news!

     Oil-type Imaging Fluids CONS

        Like bad guests, they won't go away when the party is over and need to be forcefully expelled.
        Removing the oil requires dry wiping / dilution with other hydrocarbon solvents which are volatile, and potentially
    
         
 flammable.
        Cleaning solvents solvent power must be high enough to remove tape residues. The added solvency can be
         
         
 incompatible with the
        
 drum or the coatings of some  scanner glass beds.

     Scanning fluids The Second Generation

        Main advantages: no clean up required.
        Self cleaning, evaporate  quickly  after the scan.
        Main disadvantage:
        High volatility = vapour build up,
        Highly flammable below the freezing point.
        Gasoline-like smell,
        Substances present: those  normally contained in less refined, cheaper, petroleum distillates.
        Aromatic and olefinic hydrocarbons

     The ScanScience Cup Test

Polystyrene foam is highly susceptible to attack by solvents, particularly those  containing aromatic and cyclic hydrocarbons.
As a rule, these substances have greater solvency.
The cup at the center is a new cup. The cup at the left contained LUMINA for 24 hours.  The cup at the right contained a
second generation scanner fluid during 24 hours.
Try the test yourself before trusting your film or scanner to an imaging fluid.
