Izitshixo zeminwe zinokubonwa kuyo yonke indawo ebomini bethu kwaye zisetyenziswa kakhulu.Namhlanje, uZhejiang Shengfeige uya kukuthatha ukuba uqonde iimpawu ezisisiseko zokuvala iminwe.
1. Ukhuseleko
Isitshixo seminwe yimveliso yokhuseleko eveliswe ludibaniso oluchanekileyo lwamalungu e-elektroniki kunye namalungu oomatshini.Eyona miba ibalulekileyo yezitshixo zeminwe kukhuseleko, lula kunye nefashoni.Izinga lokulahlwa kunye nezinga lokuqaphela ubuxoki ngokungathandabuzekiyo sesinye sezibonakaliso ezibalulekileyo.Basenokubizwa ngokuba lizinga lokulahlwa kunye nezinga lokuqatshelwa kobuxoki.Kukho iindlela ezininzi zokuzivakalisa:
(1) Isisombululo sentloko yeminwe esetyenzisiweyo, njenge-500DPI.
Ukuchaneka kwesensom yeminwe yeminwe ekhoyo iqhele ukuba yi-300,000 pixels, kwaye ezinye iinkampani zisebenzisa i-100,000 pixels.
(2) Sebenzisa indlela yepesenti: umzekelo, ezinye iiparamitha zibhaliwe, njl.
Kakade ke, ezi zonke iiparameters ezikhuthazwa ziinkampani ezahlukeneyo.Ingaba i-500 DPI okanye izinga lokulahlwa kwe-<0.1%, yingcamango nje yabasebenzisi abaqhelekileyo, kwaye akukho ndlela yokuyifumanisa.
(3) Ukuya kumlinganiselo othile, kuchanekile ukutsho ukuba "izinga lokugatywa kunye nenqanaba lokumkela ubuxoki" lixhomekeke ngokufanayo.Oku kubonakala kuyingcamango "yovavanyo lwe-hypothesis" kwimathematika: kwinqanaba elifanayo, ukugatywa Inqanaba eliphezulu lenyaniso, liphantsi izinga lobuxoki, kunye nelinye icala.Olu budlelwane obuphambeneyo.Kodwa kutheni ichanekile kwinqanaba elithile, kuba ukuba izinga lobugcisa kunye neteknoloji liphuculwe, ezi zikhombisi zimbini zinokuncitshiswa, ngoko ke, umgangatho wobugcisa kufuneka uphuculwe.Ukuze kukhawuleziswe isatifikethi, abanye abavelisi banciphisa inqanaba lokhuseleko ukwenza imifanekiso yobuxoki ngesantya esiphezulu kunye nokukwazi ukuqaphela okunamandla kwindleko yokhuseleko.Oku kuxhaphake kakhulu kwizitshixo zesampulu okanye kwizitshixo zedemo.
(4) Ngokwemigangatho echaphazelekayo, inqanaba lokhuseleko lweminwe yokuvala ubusela kwiingcango zokungena kwintsapho kufuneka ibe kwinqanaba le-3, oko kukuthi, izinga lokulahlwa ngu-≤ 0.1%, kwaye izinga lokuqaphela ubuxoki ≤ 0.001%.

2. Ihlala ixesha elide
1. Kwithiyori, omnye umsebenzi uthetha enye inkqubo, ngoko ke kunokwenzeka ukuba umonakalo wemveliso uya kuba phezulu.Kodwa oku kuthelekiso phakathi kwabavelisi abanamandla afanayo obugcisa.Ukuba amandla obugcisa aphakamileyo, ngoko ke iimveliso zabo zinokuba nemisebenzi emininzi kunye nomgangatho ongcono kunezo zinamandla obugcisa obuhlwempuzekileyo.
2. Inqaku elibaluleke ngakumbi kukuba: ukuthelekiswa kweenzuzo zemisebenzi emininzi kunye neengozi eziziswa yimisebenzi.Ukuba inzuzo yomsebenzi inkulu, ngoko kunokuthiwa ukunyuka kuyafaneleka, njengokuba uqhuba umda wesantya seeyadi ezili-100, awuyi kudinga ukuhlawula ixabiso lokuphulwa okanye ingozi yemoto ukuba Nyathela kwi-accelerator.Ukuba eli nqaku alikwenzeli naluphi na uhlobo, ngoko olu phawu alunamsebenzi.Ngoko ke into ephambili kukuba ungacingi ukuba "umsebenzi omnye uthetha umngcipheko omnye ngakumbi" kodwa ixabiso lomngcipheko akufanelekanga ukuthwala.
3. Njengomsebenzi wothungelwano, kwelinye icala, ukuzinza kweminwe kwinkqubo yothumelo lwenethiwekhi akuqinisekanga kushishino.Ngakolunye uhlangothi, ukutshabalalisa umhlobiso okhoyo, kwaye kubaluleke ngakumbi, xa sele ihlaselwe yintsholongwane, ayiyi kuba "iyeza" lokunyanga.Nje ukuba uqhagamshelwe kwinethiwekhi, ithuba lokuhlaselwa liya kwanda kakhulu.Kubuchwepheshe bokhuseleko obufana neealam zomnxeba, izixhobo ezinxulumeneyo kufuneka zimiselwe ngokwahlukeneyo, kwaye kukho iingxaki zemitha yangaphakathi kunye nezilumkiso zobuxoki.Ngokukodwa le yokugqibela, ngenxa yezinto zangaphandle ezifana neteknoloji kunye nokusingqongileyo ngaphandle kokutshixa kweminwe ngokwayo.
3. Anti-ubusela
1. Ngokwentsebenzo echasene nobusela, izitshixo zeminwe ezidumileyo zahlulwe zibe ziindidi ezimbini: izitshixo zeminwe eziqhelekileyo kunye nezitshixo zeminwe ezinxamnye nobusela.Izitshixo zeminwe eziqhelekileyo azahlukanga kangako kwizitshixo zoqobo ze-elektroniki.Basebenzisa ubukhulu becala uqinisekiso lweminwe endaweni yoko, kodwa azisebenzi kwiingcango ezikhoyo zasekhaya ezichasene nobusela.Olu hlobo lokutshixa lweminwe alunayo ihuku yentonga yezulu nomhlaba, kwaye ayinakusebenzisa umnyango ochasene nobusela inkqubo yokhuseleko lwezulu nomhlaba (kwimarike).Ezinye izitshixo zeminwe ezisuka kumazwe angaphandle azihlangabezani nemigangatho yoshishino lwesizwe kwaye zingasetyenziselwa kuphela iingcango zamaplanga).
2. Isitshixo seminwe esichasene nobusela sinokhuseleko olungcono kwaye sinokusetyenziswa kwiingcango eziqhelekileyo zokulwa nobusela kunye neengcango zamaplanga.Olu hlobo lokutshixa lunokuthi ngokuzenzekelayo okanye ludibanise ngokuzenzekelayo inkqubo yokutshixa kunye nesibhakabhaka kunye nomhlaba womnyango ochasene nobusela, ngaphandle kokuchaphazela ukusebenza komnyango wokuqala wokulwa nobusela.
3. Ukusebenza okuchasene nobusela kuyahluka, kwaye ixabiso lemarike lihluke kakhulu.Ixabiso lesitshixo seminwe esinomatshini wokuchasana nobusela liphezulu kakhulu kunelo lokutshixa kweminwe eqhelekileyo ngaphandle komsebenzi wokuchasana nobusela.Ke ngoko, xa uthenga isitshixo seminwe, kufuneka uqale ukhethe isitshixo esihambelanayo ngokocango lwakho.Ngokubanzi, isitshixo seminwe sikhethwa ngokweemfuno zokusetyenziswa.
4. Izitshixo zeminwe ezahlukeneyo zisetyenziselwa iinjongo ezahlukeneyo.Izitshixo zeminwe ezichasene nobusela kufuneka zikhethwe ukusetyenziswa ekhaya, ukwenzela ukuba iimfuno zomnyango ziphantsi, akukho kuguqulwa kufunwayo, kunye nokugcinwa kokuthengiswa emva kokuthengisa kulungele.Izitshixo zeminwe yobunjineli zithengwa ngokubanzi ngobuninzi, kwaye umzi-mveliso wocango nawo unokufuneka unikeze iingcango ezihambelanayo ezidibana nofakelo lwemveliso.Ke ngoko, akukho ngxaki yokuguqulwa, kodwa kuya kubakho ingxaki ekugcinweni okulandelayo okanye ukutshintshwa kwezitshixo eziqhelekileyo zokulwa nobusela, kwaye kuya kubakho ukutshixa okutsha okungahambelaniyo.Iyenzeka.Ngokubanzi, eyona ndlela ithe ngqo yokwahlula ukuba isitshixo seminwe sisitshixo seminwe yobunjineli okanye isitshixo seminwe yasekhaya kukubona ukuba ubude kunye nobubanzi bomcu wecala loxande wokutshixa (ipleyiti yesikhokhelo) phantsi kolwimi lokutshixa lwekhabhathi yocango. I-24X240mm (iinkcazo eziphambili), kwaye ezimbalwa ziyi-24X260mm, 24X280mm, 30X240mm, umgama ukusuka kumbindi wesiphatho ukuya kungqameko lomnyango ngokubanzi malunga ne-60mm.Ukubeka ngokulula, kukufakela umnyango ochasene nobusela ngokuthe ngqo ngaphandle kwemingxuma ehambayo.
